Case study Trans-European Plastics
Trans-European Plastics (TEP) is one of Europe’s largest manufacturers of plastic household items. Its French factory makes a range of over 500 products that are sold to wholesalers and large retailers throughout Europe. The company dispatches orders within 24 hours of receipt using an international carrier. All customers would expect to receive their requirements in full within one week. The manufacturing operation is based on batch production, employing 24 large injection-moulding machines. Weekly production schedules are prepared by the Planning and Control office, detailing the sequence of products (moulds and colours) to be used, the quantity required for each batch, and the anticipated timing of each production run. Mould changes (‘set-ups’) take on average three hours, at an estimated cost of A500 per set-up. Concerned about the declining delivery reliability, increased levels of finished goods inventory and falling productivity (apparently resulting from ‘split batches’ where only part of a planned production batch is produced to overcome immediate shortages), the CEO, Francis Lamouche, employed consultants to undertake a complete review of operations. On 2 January, a full physical inventory check was taken. A representative sample of 20 products from the range is shown in Table 12.7. Because of current high demand for many products, the backlog of work for planned stock replenishment currently averages two weeks, and so all factory orders must be planned at least that far in advance. The re-order quantities (see Table 12.7) had always been established by the Estimating Department at the time when each new product was designed and the manufacturing costs were established, based on Marketing’s estimates of likely demand. Recently, however, to minimize the total cost of set-ups and to maximize capacity utilization, all products are planned for a minimum production run of 20 hours. The individual re-order levels have not been reviewed for several years, but were originally based on two weeks’ average sales at that time. About 20 per cent of the products are very seasonal (e.g. Garden Range), with peak demand from April to August. Storage bins sell particularly well from October to December. The European Marketing Manager summarized the current position, ‘Our coverage of the market has never been so comprehensive; we are able to offer a full range of household plastics, which appeals to most European tastes. But we will not retain our newly developed markets unless we can give distributors confidence that we will supply all their orders within one week. Unfortunately, at the moment, many receive several deliveries for each order, spread over many weeks. This certainly increases their administrative and handling costs, and our haulage costs. And sometimes the shortfall is only some small, low-value items like clothes pegs.’ The factory operates on three seven-hour shifts, Monday to Friday: 105 hours per week, for 50 weeks per year. Regular overtime, typically 15 hours on a Saturday, has been worked most of the last year. Sunday is never used for production, allowing access to machines for routine and major overhauls. Machines are laid out in groups so that each operator can be kept highly utilized, attending to at least four machines. Any product can be made on any machine. Pierre Dumas, the production manager, was concerned about storage space: ‘At the moment our warehouse is full, with products stacked on the floor in every available corner, which makes it vulnerable to damage from passing forklifts and from double-handling. We have finally agreed to approve an extension (costing over one million Euros) to be constructed in June–September this year, which will replace contract warehousing and associated transport which is costing us about 5 per cent of the manufacturing costs of the stored items. The return on investment for this project is well above our current 8 per cent cost of capital. There is no viable alternative, because if we run out of space, production will have to stop for a time. Some of our products occupy very large volumes of rack space. However, in the meantime we have decided to review all the re-order quantities. They seem either to result in excessive stock or too little stock to provide the service required. Large items such as the Baby Bath (Item 143BB) could be looked at first. This is a good starting point because the product has stable and non-seasonal demand. We estimate that it costs us around 20 per cent of the manufacturing variable costs to store such items for one year.’
questions:
1. Why is TEP unable to deliver all its products reliably within the target of one week, and what effects might that have on the distributors?
2. What internal problems result from the current planningand control policies? In particular, analyse stock turnsand availability (e.g. high and low levels). 3 What overall recommendations would you make to Francis Lamouche about the proposed investment inthe warehouse extension?
Explanation / Answer
1 - The problem that TEP is facing is of proper management of the production chain and inaccurate estimation of the product range. As said in the case above the individual order levels were not checked for long times in the company for any products, which had lead to overstuffing of the products in their warehouse. Hence, the production of different products is taking place irrespective of any proper reorder levels, this is impacting their target of delivering within one week. It would have repercussions on the further channel of distributors, the order would fell if the said product is not delivered within time limit, once the distributors might give a blind eye, but if this keeps on going, this would be disastrous for TEP, it would lead TEP to downfall as orders would stop coming as they could not deliver in given time range.
2 - Currently, In TEP the Planning and control policies are old school and have not been reviewed for ages. This needs to be changed, due to that proper planning of the production of different product range could not be planned and said product could not be delivered within the time range, this could have long-term issues. As the Different team have different estimates and do not have coordination between them, this would further lead to more clashes and would affect the production as well as finances of the company. Plus due to wrong estimations, the stock is piling in the warehouse of the products which are not the best sellers in the season, this could be avoided by doing proper research and reworked estimations.
3 - The Warehouse needs an extension due to the evergrowing pile of stock, this could be avoided if the company tries to adopt techniques like Just in Time, this would help the company to keep the inventory minimal, plus this would help in keeping proper log of the demand for a particular product and schedule its production accordingly. And if the extensions in a must then the warehouse should be designed in such a way that products are to be divided into different sections like bath range, garden range etc and to be stored in their sections and if the area is full further production to be stopped in that area, this would lead the estimations team to work harder and get near range of the demand.
