İleri teknolojili imalat sistemleri için yatırım değerlendirme modeli

Economic Performance Model The aim of this model is to use the configuration information and cost data to evaluate economical performance of all systems and transfer the outputs to a strategic performance module and decision model: In this model, the main criteria; unit cost, was calculated by activity based cost planning. The elements thought to contribute to unit cost are: Depreciation, labor, in spection, scrap and rework, material, space.maintenance, tool, fixtures, computer programming, work in process, inventory, overheads(energy, heating, light*cleaning etc. ), and set-up cost. The other criterion are selected by commonality in usage which are return on investment, payback period, net present value and total manufacturing cost. Strategic Performance Module This module as works by the outputs of the operational and economic performance mo dels to produce non-monetary information about alternative systems for the decision model. Quick delivery, delivery reliability and adoption into new manufacturing conditions are tested in the module. Another function of the module is sensitivity analyses of the systems. Decision Model In the investment decision, the present and the future situation of the market should be ta ken into consideration. The technology level of the company and product life cycle are used in combination as below, Saturated Market - Technology Leader Saturated Market - Technology Follower Growing Market - Technology Leader Growing Market - Technology Follower The model was built on the basis of Analytic Hierarchy Process Method. The output of the model are the priorities of the alternative systems in which the system with the highest priority is elected as an investment candidate. The model which was developed has the properties stated below. - The model can also be used to examine the situation of the present system. xv
