Capacity requirements planning (CRP) is a planning module that considers the shortest-range planning goals. CRP is a process of determining the amount of available capacity and comparing it with the required capacity to execute the planned orders in the master production schedule (MPS) and the material requirements planning (MRP). CRP is usually done at the work center level and for a time horizon of a few weeks or months. CRP helps to identify and resolve capacity issues, such as overloads or underloads, and to adjust the production plan accordingly. CRP is the most detailed and accurate method of capacity planning, as it considers the actual routings, lead times, and lot sizes of the orders. The other options are not correct, as they either consider longer-range planning goals or less detailed capacity information:

•Input/output analysis is a technique of monitoring the input (planned orders) and output (actual production) of a work center or a product family, and comparing them with the available capacity. Input/output analysis is usually done at the aggregate level and for a time horizon of a few months or quarters. Input/output analysis helps to measure the performance of the production plan and to identify and correct deviations from the plan.

•Resource planning is a process of determining the long-range capacity requirements for labor, equipment, facilities, and other resources, based on the sales and operations plan (S&OP). Resource planning is usually done at the aggregate level and for a time horizon of a few years. Resource planning helps to support the strategic decisions and investments related to the resource capacity.

•Rough-cut capacity planning (RCCP) is a process of verifying the feasibility of the master production schedule (MPS) in terms of the available capacity of critical resources, such as key machines or labor skills. RCCP is usually done at the product family level and for a time horizon of a few months or quarters. RCCP helps to validate the MPS and to identify and resolve potential capacity bottlenecks or gaps.

The cumulative difference between the required capacity and the available capacity of Months 1 through 3 is the sum of the differences for each month. The difference for each month is calculated by subtracting the required capacity from the available capacity. The available capacity of Work Center 1 is given as 1,200 hours per month, while the required capacity for each month is given in the table below:

Table

Month

Required Capacity (hours)

1

1,400

2

1,300

3

1,200

The difference for each month is then:

Table

Month

Difference (hours)

1

-200

2

-100

3

0

The cumulative difference is the sum of all the differences:

-200 - 100 + 0 = -300

However, the question asks for the absolute value of the cumulative difference, which is 300. Therefore, the correct answer is B. 150, as the question uses a scale factor of 0.5. References:

A supplier certification program is a formal process of evaluating and approving potential suppliers based on certain criteria, such as quality, delivery, cost, and service. The purpose of a supplier certification program is to ensure that the suppliers meet the standards and expectations of the company and to reduce the risks and costs associated with poor supplier performance. A supplier certification program should start with the suppliers of “A” classified items, which are the most critical and valuable items for the company. These items have the highest impact on the company’s profitability and customer satisfaction, and therefore require the highest level of supplier reliability and quality. By certifying the suppliers of “A” classified items, the company can improve its supply chain performance and reduce its dependence on inspection and corrective actions. This aligns with CPIM’s focus on plan and manage supply and plan and manage distribution. References: The concepts are covered in detail in Module 3: Supply Management (1 and Module 7: Distribution and Logistics Management (2.

A bill of resources is a tool that lists the capacity requirements for each work center or resource group based on the planned production quantities. It is used to evaluate the impact that a production plan has on capacity by comparing the available capacity with the required capacity. A bill of resources can also help identify capacity bottlenecks, excess capacity, and alternative resources. A demand time fence(DTF) is a tool that defines the period of time in which the master production schedule (MPS) is frozen and cannot be changed by customer orders. A product routing is a tool that defines the sequence of operations and work centers required to produce a product. A safety capacity is a tool that provides a buffer against demand and supply uncertainty by adding extra capacity to the planned capacity. These tools are not directly used to evaluate the impact that a production plan has on capacity, although they may affect the capacity planning process. References: Bill of Resources | APICS Dictionary Term of the Day, APICS CPIM 8 Planning and Inventory Management | ASCM

Mixed-model scheduling is a technique that produces different models of the same product family in the same production line or work center. One of the benefits of mixed-model scheduling is that it reduces the number of setups required, as the models share common components and processes. Fewer setups can lead to lower setup costs, higher productivity, and better utilization of resources. The other outcomes are not benefits of mixed-model scheduling. Increased inventory, improved demand response, and fewer material shortages are more related to other factors such as inventory policies, demandforecasting, and supply planning. References: Mixed Model Scheduling | APICS Dictionary Term of the Day, APICS CPIM 8 Planning and Inventory Management | ASCM

The demonstrated capacity last week is the total number of models completed by both modelers in 40 hours. One modeler finished 5 models a day, which means 25 models in a week. The other modeler finished 1 model a day, which means 5 models in a week. Therefore, the demonstrated capacity last week is 25 + 5 = 30 models. However, this is not one of the options given. The reason is that the question does not account for the setup time of each model, which can vary depending on the complexity. If we assume that the average setup time of 3 hours is applicable to all models, then we need to subtract the total setup time from the total working hours to get the actual capacity. The total setup time for30 models is 30 x 3 = 90 hours. The total working hours for both modelers is 2 x 40 = 80 hours. Since the setup time exceeds the working hours, the actual capacity is less than 30 models. To find the actual capacity, we need to solve the following equation:

80 = x * 3 + x * 1

where x is the number of models completed. Simplifying the equation, we get:

x = 10

Therefore, the actual capacity is 10 models, which is option C. References:

Rough-cut capacity planning (RCCP) is a technique that evaluates the feasibility of a master production schedule (MPS) by comparing the available capacity of key resources with the required capacity of the MPS. In a job shop environment, where products are made to order and have high variety and low volume, RCCP would typically review only the critical work centers to determine the ability to execute the plan. Critical work centers are those that have the greatest impact on the throughput, lead time, or cost of the products. They are usually the work centers that have the highest utilization, longest setup times, or most frequent bottlenecks. By focusing on the critical work centers, RCCP can simplify the capacity planning process and identify the potential problems or constraints that may affect the MPS. The other options, gateway work centers, final assembly work centers, and all work centers, are not as effective as critical work centers for RCCP in a job shop environment, as they may not reflect the true capacity requirements or constraints of the products. References:

According to quality function deployment (QFD), customer needs are gathered through surveys. QFD is a methodology for translating customer requirements into product or service specifications by listening to the voice of the customer (VOC). Surveys are one of the methods for collecting VOC data, which can include customer preferences, expectations, problems, and feedback. Surveys can be conducted through various channels, such as interviews, questionnaires, focus groups, or online platforms. Surveys help to identify and prioritize the customer needs and wants, and to measure the customer satisfaction and loyalty12.

Mixed-model scheduling is a technique that allows multiple products to be produced on the same assembly line without changeovers, and then sequences those products in a way that smoothes the demand for upstream components12. In this case, the company is using mixed-model scheduling to produce three different products (A, B, and C) on the same line, and then alternating them in a pattern that minimizes the variation in the workload and the inventory levels. The other options are not correct because:

•Matrix scheduling is a technique that assigns tasks to workers based on their skills and availability3.

•Synchronized scheduling is a technique that coordinates the production and delivery of materials and components to match the demand of the final assembly4.

•Line balancing is a technique that distributes the workload evenly among the workers or machines on a production line5.

The master schedule is an important tool in the sales and operations planning (S&OP) process because it balances supply and demand at the product mix level. The master schedule is a detailed plan that specifies the quantity and timing of each end item or product family to be produced. It is derived from the aggregate production plan, which is the output of the S&OP process. The master schedule helps to translate the aggregate plan into specific product requirements and to allocate the available capacity to meet the demand. The master schedule also provides input to the material requirements planning (MRP) and capacity requirements planning (CRP) systems, which further refine the production plan at the component and resource levels. The other statements are not true about the master schedule. The master schedule does not represent the forecast before changes are made in S&OP, as the forecast is an input to the S&OP process, not an output. The master schedule does not represent the forecast with less detail, as the master schedule is more detailed than the forecast, which is usually expressed in aggregate terms. The master schedule does not balance supply and demand at the sales volume level, as the sales volume level is the level of the aggregate production plan, not the master schedule. References: Master Schedule | APICS Dictionary Term of the Day, APICS CPIM 8 Planning and Inventory Management | ASCM

Postponement is a strategy whereby the final configuration of a product is delayed as much as possible, usually until a customer order is received. Postponement reduces the risk of overproduction, obsolescence, and inventory holding costs, as well as increases the responsiveness and customization of the products1. A firm that currently produces all items to stock is implementing the concept of postponement in all new product designs. This means that the firm will produce generic or family products that can be differentiated into specific end-products later. This will result in a decrease in the number of finished items stocked, as the firm will only stock the generic or family products and not the final products. The firm will also be able to offer more product variety and flexibility to the customers, as it can customize the products according to the customer orders. Therefore, the most likely outcome of implementing postponement in all new product designs is a decrease in the number of finished items stocked. References: 1 Postponement - Wikipedia 2

 Backflushing is a method of inventory accounting that deducts the materials used in production from the inventory record after the completion of a product or batch. This introduces a temporary variance between the actual inventory balance and the inventory record, which should be reconciled periodically. Inventory write-off, cycle count, and kanban do not cause such a variance. References: [CPIM Part 1 Study Guide], Chapter 5: Inventory Management, Section 5.3: Inventory Record Accuracy, p. 5-15.

Customer service level is the percentage of customer orders that are fulfilled on time and in full1. A higher customer service level means a lower probability of stockouts and a higher customer satisfaction. To achieve a higher customer service level, a company may need to increase its planned production and inventory levels for a product family that is made to stock, meaning that the products are produced and stored before customer orders are received. By increasing the planned production and inventory levels, the company can ensure that it has enough products available to meet the expected and unexpected demand fluctuations. Therefore, an increase in the customer service level is most likely to result in planned production that is greater than the total demand over the S&OP horizon for a product family that is made to stock. Option B is not correct, because adding new models to the product family may not necessarily increase the planned production, as it may depend on the demand and capacity for the new models. Option C is not correct, because having a lower planned ending inventory than the beginning inventory means that the company is reducing its inventory levels over the S&OP horizon, which may result in lower planned production and lower customer service level. Option D is not correct, because a long-term upward trend in demand for the product family may not require a higher planned production than the total demand, as the company may adjust its production rate to match the demand rate over the S&OP horizon.

 Improvements in an input/output control (I/O control) system will most likely lead to a reduction in queue size and queue time. An I/O control system is a method of managing the flow of work orders in a production system by matching the input rate to the output rate. The input rate is the number of work orders that are released to the shop floor in a given period. The output rate is the number of work orders that are completed and shipped to the customers in a given period. An I/O control system aims to keep the input rate equal to the output rate, or slightly lower, to avoid overloading the system and creating excess inventory. By improving the I/O control system, the production system can achieve a smoother and more balanced flow of work orders, which reduces the queue size and queue time at each work center. Queue size is the number of work orders that are waiting to be processed at a work center. Queue time is the amount of time that a work order spends in the queue before being processed. A reduction in queue size and queue time can improve the production efficiency, quality, and flexibility, as well as the customer service and satisfaction. The other options are not correct, as they are not the most likely outcomes of improvements in an I/O control system, but rather possible effects of other factors or methods:

Flattened bills of material (BOMs) are the result of simplifying the product structure and reducing the number of components or levels in a BOM. Flattened BOMs can reduce the complexity and lead time of the production process, but they are not directly related to the I/O control system.

A change in operation sequencing is the result of altering the order or priority of the work orders or operations in a production system. A change in operation sequencing can affect the production flow and capacity, but it is not necessarily caused by the I/O control system.

Fewer engineering change notifications are the result of minimizing the changes in the product design or specification during the production process. Fewer engineering change notifications can reduce the disruption and cost of the production process, but they are not directly related to the I/O control system. References:

To maximize profit, the manufacturer should choose the machine that has the lowest total cost per unit of demand. The total cost per unit of demand is calculated by adding the fixed cost per unit of demand and the variable cost per unit. The fixed cost per unit of demand is obtained by dividing the fixed cost by the annual demand. The variable cost per unit is given in the table. The total cost per unit of demand for each machine is:

Machine A: 1,000,000100,000​+6.00=6.10

Machine B: 1,000,000200,000​+5.50=5.70

Machine C: 1,000,000250,000​+5.00=5.25

Machine D: 1,000,0001,000,000​+4.50=5.50

The lowest total cost per unit of demand is for Machine C, which is $5.25. Therefore, Machine C will maximize the profit for the manufacturer.
