CLIL CLIL LANGUAGE IMMERSION DESIGN AND INDUSTRIAL ORGANIZATION PRODUCTION TECHNIQUES The competitive nature of the manufacturing industry means that companies are constantly looking for ways to increase the efficiency and productivity of their systems. Three of the most important ways companies can realize this are by using standard components, modular systems and different production methods. It is common practice in modern manufacturing for the production of the components that make up a product to be given to external companies. The advantage of using standard components is that it speeds up manufacturing and reduces manufacturing and maintenance costs, as the same units can be purchased and used all around the world. As the electronics used in products have become more complex, many manufacturers have adopted a modular approach to control systems. Modular systems have the following advantages: they allow inputs, processes and outputs to be combined permanently or temporarily, and they make replacements and upgrades easier, because only the broken/ obsolete part needs a replacement/upgrade. Entrepreneurs need to decide which production method is best for them. There are three main production methods used in manufacturing: oneoff, batch and mass production. One-off production Sometimes known as job production, this is where a single item is required; for example, a suspension bridge or a custom-made engine for a racing car. The unit cost is high for this method, as the production system needs to be changed for each different unit. Batch production This happens where quantities of an item are sold regularly; for example, a local baker producing many batches of specialist loaves each day for sale in local shops. Batch production will involve producing and storing the components which will make up the end product. Mass production Products that sell in high volume, nationally or internationally, are manufactured on production or assembly lines. The initial set-up cost (or capital investment) of mass production is high, due to the specialist equipment used but the cost is spread across a very large number of products so the unit cost is low. When a mass-production line runs continuously round the clock, it is called continuous flow. The best method of production depends on the type of product being made and the size of the market. Small firms operating in the service sector, such as plumbers, use one-off production because each customer has individual needs. Batch production is used to meet group orders while flow production is used to mass produce everyday standardized items. Economies of scale lead to lower unit costs and prices but not many small manufacturers can afford the investment needed to mass produce goods, so they often opt for either batch or one-off production. 140
