Explanation

RFID tags are the small devices that can be embedded in labels or attached to tags which work with radio transmitters and/or receivers to identify themselves.

RFID tags can be used to do the following:

- Track individual items

- Track boxes of products, cages of products and pallets

- Track containers with multiple loads

- Locate equipment within a building

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

RFID devices have a 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.

RFID operating rage depends on the radio frequency used, receiver capability and the environment. Some tags are only readable from under 1m, others can have a 100m range.

RFID tags and labels are very specific to the type of material and size of your assets. For example, metal will deactivate the RFID antenna and the tag will not transmit at all. Using RFID on metal requires a special type of tag with an RFID block to prevent interference with the antenna. Liquid products can also affect the reliability of the RFID signal. To use RFID tags in specific environ-ments, some technologies are needed to support them.

Explanation

Radio frequency identification (RFID) are items which use radio technology to identify itself and its location subject to having appropriate hardware and software.

RFID tags are made of three different components: an RFID chip, which is an integrated circuit (IC), an antenna, and a substrate.

A RFID Reader is a device that uses radio-frequency waves to wirelessly transfer data between itself and a RFID tag/label in order to identify, categorize and track assets. When combined with the right RFID software, a RFID reader can identify objects quicker, more accurately, at a reduced overall cost, and at various points of the object’s lifecycle.

Passive RFID systems use tags with no internal power source and instead are powered by the electromagnetic energy transmitted from an RFID reader. Passive RFID tags are used for applica-tions such as access control, file tracking, race timing, supply chain management, smart labels, and more.

Active RFID systems have three essential parts – a reader or interrogator, antenna, and a tag. Ac-tive RFID tags possess their own power source – an internal battery that enables them to have ex-tremely long read ranges as well as large memory banks.

Explanation

Direct and indirect costs of holding inventory include the following:

1. Acquisition costs

2. Holding costs (carrying costs) are the costs associated with the storage and handling of physical stock. There are two different types of holding costs:

a. Costs related to the value of the goods: financial costs (i.e. the interest on the working capital tied up in inventory, which may be the bank borrowing rate or the company's target for return on capital); cost of insurance; losses due to product deterioration; losses due to obsolescence and redundancy of inventory; losses due to theft, accidental damage etc.

b. Costs related to the physical characteristics of the inventory include the following: storage space; power, heat and lighting of the store; movement equipment; labour costs; administration costs.

3. Costs of stockouts

Explanation

Fixed-Time Period System (or Periodic Review system) is the inventory management system in which inventory is checked in fixed time periods, T, and the quantity ordered varies. The system also contains a target inventory level, R, which is restored when order received. The order quantity is calculated as:

Q = R – IP

where: Q = order quantity

R = target inventory level

IP = inventory position

Inventory position (IP) is equal to inventory on-hand plus quantity on order minus backorder (if any)

The order quantity varies because the inventory position at each review point differs from each other.

Just-in-Time (JIT) aims to:

Improve quality by ensuring defect-free products that meet customer expectations.

Reduce inventory levels: The JIT approach minimizes holding costs by producing and delivering goods as needed.

Whole-life asset management values JIT for optimizing inventory control, reducing waste, and enhancing quality while keeping storage costs minimal.

Explanation

Lean thinking aims to remove wastes from work processes. Before diving into the 8 wastes, it is important to understand what waste is. Waste is any action or step in a process that does not add value to the customer. In other words, waste is any process that the customer does not want to pay for.

The original seven wastes (Muda) was developed by Taiichi Ohno, the Chief Engineer at Toyota, as part of the Toyota Production System (TPS). The seven wastes are Transportation, Inventory, Motion, Waiting, Overproduction, Overprocessing and Defects. They are often referred to by the acronym ‘TIMWOOD’. The 8th waste of non-utilized talent or ‘Skills’ of workers was later introduced in the 1990s when the Toyota Production System was adopted in the Western world. As a result, the 8 wastes are commonly referred to as ‘TIMWOODS’.

Explanation

Material requirement planning (MRP) is a production planning and material (inventory) control system used in manufacturing. Objectives of MRP are to ensure materials are available for production while minimising inventory and to plan production and procurement activities.

MRP process is described in the graph below:

Indirect stock refers to items that are necessary for the operation of the manufacturing process but are not incorporated into the finished product. Examples include maintenance supplies, office consumables, and tools. In whole-life asset management, indirect stock management ensures that essential operational items are available without tying up excessive capital in inventory that doesn’t contribute directly to production output.

Explanation

Organisations often create their own stock keeping unit (SKU) numbering system, which may or may not have a meaningful structure. Stock keeping unit is a number that is assigned to a product for the purpose of inventory management and is of tracking. In other words, a stock keeping unit is a unique identifier assigned to each product for easier and more efficient record keeping.

An FDA (US Food and Drug Administration) product code describes a specific product and contains a combination of five to seven numbers and letters. The product code submitted with each FDA line item should match the actual product name and/or invoice description of the product.

The International Standard Book Number is a numeric commercial book identifier which is in-tended to be unique. Publishers purchase ISBNs from an affiliate of the International ISBN Agency.

The Harmonized Commodity Description and Coding System, also known as the Harmonized System (HS) of tariff nomenclature is an internationally standardized system of names and numbers to classify traded products.
