SUSVÎMÂRY A SOFTWARE SOLUTON İN A TEXTILE COMPANY Today in Turkey, many organizations use computers and software solutions. Contrary to general belief, having computers and computing povver won't solve a coorporations managament problems as, especially production managament usually is too human dependent; so the aim is finding the appropriate solutions for the problems for a given set of prerequisites. Some managament problems need special solutions which results in developing new software. The software must be reliable and efficient; it should easily be adapted to the changing needs of the coorporation. and must be accepted and trusted by the user. A certain level of responsiveness and speed must be maintained since a user sees a computer (and the softare running on it) as a tool and a slow, unresponsive tool is usually the root of user dislike. Development of such a softvvare have several steps : *Examining the problem *Finding a feasible solution » Choosing development team, environment and tools *Implementing the solution » Implementing corrections and improvements The Problem The basic problem was the“Information Flow”. in every step from the order to the shipment, there were breaks in the information flow. The company could not provide the customer an accurate delivery time. This resulted in lost opportunities in terms of probable orders. Errors in cost estimation resulted in underpricing and overpricing. Lack of information caused erroneous material planning: there vvere unwanted material stocks ör shortages. Overtime costs were high. Production monitoring was inadequate; batch sizes were not correct. The management had no direct control över the production cyce and this resulted in employee distress since xFunction 1 This function defines the consolidated requirements. Using the unit consumptions in each model, this function yields the total requirement for each model. Consolidating each model yields the total requirement for the whole production batch. Function 2 Excess material from previous orders affects the amount to order. The consolidated model requirement minus excess material yields the total amount to order for this period. Function 3 One of the major problems of the textile industry is that the amount of material received may be different than the ordered amount. As a result of the orders the company can get more or less than the ordered amount. For 950 m required amount the order is 1000 m. When the consumption is recalculated, the required amount may change to 1080 m. Classic software can solve this problem by making an extra order. Actually the amount company got is 1100 m and there may be no need for extra order. Function 4 Actual used amounts affects the next order for the same model and this makes the fourth function. There are two conditions for this function. 1. The material used in production is less than the calculated amount. The next order must be calculated for these new consumption amounts. 2. The material that has to be used in production is more than the ordered amount. In real life, this second condition appears more.
