Explanation

Many codes have integrated check digits. These are additional numbers or characters added to codes that a computer uses to verify the number is valid. The intention is to reduce the likelihood of miskeying an item and hitting an alternative live item. More often, a system is devised which a computer can calculate using combination of numbers.

Barcode is a graphic symbol used to convey data. Typically the characters in a barcode symbol consist of bars/space pattern. Barcode is the method of representing data in a visual, machine-readable form. Initially barcodes represented data by varying the width and spacing of parallel lines.

Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects.

A prefix is an affix which is placed before the stem of a word or a string. A product code may have prefix which indicates its group, country, origins, etc.

Explanation

Net present value (NPV) is the 'today' net value that deprives from 'future' cash flow of an invest-ment or a capital purchase.

The following formula is used to calculate NPV

Chart Description automatically generated with low confidence

Where:

Rt is the net cash flow (cash inflow - cash outflow) during the period t

i is the discount rate

t is the number of time periods

As you can conclude from the above formula, the net present value increases when the numerators (net cash flows) increase and/or denominators (1+i) decrease. So the correct answer should be "Net cash flow during a time period increases"

The purpose of this exercise is to help you identify the factors that influence the net present value and how to increase/decrease NPV in real-world scenario.

Explanation

RFID tags have very limited range. The following table was extracted from Wikipedia:

RFID tags can be used to do the following:

- Track individual items

- Track boxes of products, cages of products and pallet

- Track containers with multiple loads

- Locate equipment within a building

- Trigger alarms should equipment or stock be removed without authorisation.

RFID tags are made of three different components: an RFID chip, which is an integrated circuit (IC), an antenna, and a substrate. RFID chips are very small integrated circuit incorporating a small memory capability - many are smaller than 2mm square and 2mm thick. Despite its size, many can hold 2000 characters of data. Many retailers simply use the tag as a thick label and print both sides with product information and perhaps a barcode.

It is important to note that there are multiple standards in use for RFID - some of these are standardised for industries but there are also national standards in operations. These standards need to be investigated before investment as not all readers work with all cards. GS1 is a non-for-profit organisation which make the standards for barcodes and RFID.

Explanation

The total cost of storage consists of two different costs:

- The cost of warehouses: each one has a different cost, and each has the cost of stock-holding and stock management included

- The transport costs: the total transport cost reduces as further warehouses mean shorter final delivery to the customers.

Depending on each situation, the optimal number of warehouses varies. Generally, more facilities will increase the cost of warehouses while reduce the transport costs and vice versa.

Explanation

In principle, use of any materials involves an environmental cost. Some packaging materials use a lot of natural resources and energy to produce. The journey taken by packaging from raw material to manufacturing and then to the initial user also incurs a 'carbon footprint'. The weight of packag-ing contributes to the fuel usage of vehicles while the volume used can add up to additional jour-neys or the use of larger vehicles. Finally, the reuse, return, disposal or recycling will also involve additional to the environmental cost.

In this question:

- 'Purchase the packaging materials in bulk' may incur additional fuel and carbon footprint in delivering these materials

- 'Try to reduce the costs of packaging' may prompt the organisation to use less eco-friendly and cheap materials like polystyrene chips

- 'Not use the packaging materials at all' can increase the environmental performance of packag-ing activities, but it also harms the products to be delivered and may cause other environmental problems (i.e. spillage of toxic chemicals into the environment)

So the correct answer should be: 'Adopt international environmental packaging standards'. The International Standards Organisation (ISO) has published several standards regarding packaging and environment, namely ISO 18601, ISO 18602, ISO 18603, ISO 18604, ISO 18605, ISO 18606.

A contract for hire allows the hirer to use the item for an agreed period and rate, without ownership transferring. This option provides flexibility and avoids the financial commitment of ownership, aligning with whole-life asset management when short-term use or flexibility is more beneficial than purchase.

While storage space is important, traffic flow and accessibility are crucial for efficient warehouse design. Proper layout ensures safe, quick movement of goods and minimizes bottlenecks, reducing operational costs and enhancing efficiency. In whole-life asset management, effective space utilization and efficient layout planning are key for long-term warehouse performance.

Explanation

An exponential moving average (EMA) is a type of moving average (MA) that places a greater weight and significance on the most recent data points. The exponential moving average is also referred to as the exponentially weighted moving average. An exponentially weighted moving average reacts more significantly to recent price changes than a simple moving average (SMA), which applies an equal weight to all observations in the period.

Explanation

If the planning and mitigation measures fail and redundant or obsolete stock is identified, it needs to be removed from the current inventory location as quickly as possible. There are some methods to deal with these types of stock. The worst case scenario is disposal to landfill, which is inadvisable if it can be avoided, both from environment point of view and the financial costs of such disposal.

For example, the problem of obsolete pesticides remains extremely serious and urgent. Many of the stocks identified continue to deteriorate thereby giving rise to an ever escalating source of severe pollution and posing a threat to human health, the environment and development in particular. To reduce the impact of obsolete pesticides on environment, FAO initiated a project in Yemen in which a total of 262 tonnes of obsolete pesticides were removed from 20 different sites and successfully disposed of between March and June 1996. The major field operation was completed in six weeks during which period almost all obsolete pesticides were brought to a central location and subsequently shipped to the United Kingdom for incineration.

Explanation

Warehouse dock is a feature of warehouse design - used for unloading and loading vehicles. It is crucial to carefully design where they are externally located in a facility and choose the best type of dock depending on the available space.

In many cases efficient and effective loading and unloading is achieved by a dock design that places the loading and unloading vehicle' rear platform at the same height as the warehouse floor.

Slopes in docking areas must always be as small as possible: the gentler the slope, the less chance of errors and accidents. If a warehouse is going to be used by large volume vehicles, such as high cubes, it may be necessary to install special devices, such as hydraulically adjustable docks or ground level lift platforms.

Current trends indicate that vehicles that are longer and wider and have a greater volume will be increasingly common. Therefore, when planning the location of the docks, it would be useful to ensure that there is a large area for the approach, manoeuvring and build-up of large vehicles.

One option to increase the efficiency of the docks is to combine reception and dispatch into a single area (dual use). This solution drastically reduces costs and, above all, increases the use of handling equipment and personnel. However, if this is justified by the volume of material flows, there can also be separate access points for each function (some for reception and others for dispatch - 'sole use').
