Explanation

Total productive maintenance (TPM) is an innovative concept in the manufacturing industry that evolved from the idea of preventive maintenance to adopt practices of productive maintenance, maintenance prevention, and reliability Engineering. What we now refer to as TPM, has become an ingenious approach to achieve overall equipment effectiveness by involving the workforce behind the machines (i.e. the operators).

8 pillars of TPM

1) 5S - Sort, straighten, shine, standardize, and sustain

Just like a physical structure starts with a grounded framework, building a strong TPM process requires a strong foundation in the form of the principles of 5S. This is a workplace organization method that is simplified into 5 basic steps:

Sort tools, equipment, and materials to identify which of these can be discarded

Straighten and set things in proper order to reduce unnecessary motion and efficiently travel be-tween working groups and locations

Shine refers to performing necessary housekeeping to clean up the work area

Standardize and schedule activities to systematically form the habits to keep the workplace orga-nized

Sustain the process and principles for long-term applications

The 5S approach provides a systematic approach to cleaning the workplace, thereby uncovering underlying problems and challenges.

2) Autonomous maintenance

Maintenance tasks and caring for equipment should start with the people using the equipment. The empowerment of operators to work on small maintenance tasks effectively allows the maintenance teams to focus on more specialized assignments.

3) Continuous improvement

Also known as the Japanese term Kaizen, Continuous Improvement promotes the attitude of pro-gressing towards zero losses and zero defects. Through small but continual tweaks to processes, the overall effectiveness and efficiency of the organization is developed.

4) Planned maintenance

Planned maintenance activities are essential to the prevention of equipment breakdown. Planned maintenance is performed by periodically evaluating the condition of equipment to proactively prevent deterioration and mechanical failures.

5) Quality maintenance

To ensure the satisfaction of the customer, manufacturing processes aim for zero-defect production. Standards for superior quality, and checks on whether the standards are being met, should be in place. The goal of quality maintenance is to identify any possible causes of deviations from zero-defect production.

6) Training

The idea of TPM is that everyone does their part to contribute to the overall productivity of the production process. In order to achieve optimum performance, and to build each member’s competence, proper training is required to equip each one with the theoretical and practical know-how of working with machines and equipment.

7) Office TPM

A key role that is often overlooked is the administrative department that works behind the scenes. Like the rest of the production teams and processes, the management and administrative functions are also subject to productivity improvement. Tins includes identifying and eliminating losses, and contributing to the overall performance of the plant.

8) Safety, health, and environment

The last of the eight pillars focuses on creating a safe workplace. The essence of this pillar is real-ized when actively applied to each of the other pillars. The successful implementation of this pillar will contribute to a secure and hazard-free workplace.

Explanation

The product code is often the key to obtaining documentation relating to products.

Product codes are often use to link to internal processes. Some computerised inventory systems trigger alerts when specific items or volume are ordered - this could be an out-of-stock warning or potential volume errors.

In many cases, an organisation will use its own product code system. The organisation constructs a code that is effective and fits with its software and the variety of items covered. So these codes may or may not comply with any international standards (such as GS1 specifications, ISO standards, etc.). As organisations make up the code themselves, the codes may look identical to others. For example, SKU414675 reveals that it is used for many items, including the following:

- A UK wholesaler's six-pack of branded cola

- An Australian snack food

- UK flower seeds

- An Italian desk sold in Japan

- A Brazilian light fitting

Explanation

The safety stock (or buffer stock) is the stock level that limits stock shortages due to unforeseen events (forecasts not in line with demand, longer than expected supply time, etc…)

Demand variance is the degree to which the demand in a fixed period deviates from the average demand of the same period.

A reorder point is the unit quantity on hand that triggers the purchase of a predetermined amount of replenishment inventory.

The just-in-time (JIT) inventory system is a management strategy that aligns raw-material orders from suppliers directly with production schedules.

Explanation

RFID tags are made of three different components: an RFID chip, which is an integrated circuit (IC), an antenna, and a substrate. RFID Antennas are necessary elements in an RFID system be-cause they convert the RFID reader’s signal into RF waves that can be picked up by RFID tags. Without some type of RFID antenna, whether integrated or stand-alone, the RFID reader cannot properly send and receive signals to RFID tags.

Explanation

Fixed assets may be sold anytime during their useful life. This gives rise to the need to derecognize the asset from balance sheet and recognize any resulting gain or loss in the income statement.

The accounting for disposal of fixed assets can be summarized as follows:

- Record cash receive or the receivable created from the sale:

Debit Cash/Receivable

- Remove the asset from the balance sheet

Credit Fixed Asset (Net Book Value)

- Recognize the resulting gain or loss

Debit/Credit Gain or Loss (Income Statement)

Example

ABC LTD purchased a machine for $2000 on 1st January 2001 which had a useful life of 5 years and an estimated residual value of $500. The machine was being depreciated on straight line basis. However, ABC LTD decided to sell the asset on1 January 2003 for $1500 in order to raise cash for the purchase of a new machine.

The disposal of the fixed asset will be recorded as follows:

Record cash received or the receivable arising from the sale:

Debit Cash $1,500

Remove the asset from the balance sheet

As a fixed asset is recognized in the balance sheet at the Net Book Value (i.e. Cost less Accumulated Depreciation), the machine will be removed from the accounts of ABC LTD in two parts:

First, the Machine Cost must be removed by crediting the ledger:

Credit Machine Cost $2,500

Second, the Accumulated Depreciation in respect of the machine must be removed by debiting the ledger:

Debit Accumalated Depreciation $600*

*Accumulated Depreciation: (2000 - 500)/5 x 2 Years

The combined effect of the above two transactions would be to remove the machine's net book value of $1400 (2000 - 600) from the balance sheet.

Recognize the resulting gain or loss on the sale of machine

ABC LTD received $1500 for an asset with a balance sheet worth of $1400. It therefore earned a gain of $100. The gain will be recorded as follows:

Credit Gain on Disposal $100

Explanation

ABC classifications are applied to stock and its management is based loosely on the Pareto princi-ple, better known as the 80/20 rule.

The likely outcome of analysis of inventory (value importance):

- Category A - about 20% of the stock items account for about 80% of the total inventory value. Items in category A have the highest value.

- Category B - about 30% of items account for about 15% of total inventory value

- Category C - the remaining 50% of items account for 5% of the total inventory value

Just-in-Time (JIT) inventory management minimizes stock levels by synchronizing orders with production schedules, which:

Reduces holding costs: Less inventory means lower costs for storage and management.

Increases cash flow: Reduced stock levels free up working capital.

Whole-life asset management supports JIT as a cost-saving measure, focusing on maintaining lean inventories while meeting production needs.

Explanation

Possible solutions to the high irregular or seasonal demand problems are listed below:

• Take advantage of the height of the warehouse

- Mezzanine floor

- High racking system (increase storage capacity but require high-reach material handling equip-ment)

• Eliminate dead stock or inventory

• Improve material flow

• Improve storage location method

• Consider using aisle space during demand peak

• Narrow aisles between racks (require narrow handling equipment)

• Carousel-type storage system

• Auto-storage and retrievals system (ASRS)
