Özet:

This study focuses on the basic concepts of supply and demand balance, capacity, economies of scale and scope, theoretical and practical integrated research problems, solution possibilities and techniques.in the production processes, supply chain, combined transport main services processes. The study investigated medium and long-term capacity and scale economies, supply and demand balance fluctuations, requirements and qualifications, possible variations of production, the techniques of economically describing and determining, economies of scale and scope. Economies of scale and scope compliance levels of companies in Turkey was searched by the information gathering form organized within the scope of the study. It was found that scale and scope economies are higher in companies operating in the field of logistics than manufacturing firms and It was determined that the firms had development areas to increase the economies of scale and scope levels. It is clear that average demands in long-run business sub-processes have emerged under the capacity of scale economies. This way of working was dealt with based on diversity of operating production due to fluctuations in demand and on reducing the idle capacity and reducing the average unit costs. The study investigated relations between opportunity cost, unit average cost, linear programming and break-even techniques integrated in the direction of the method of determining production varieties. It has been seen that the logistics, upstream and downstream services of the supply chain processes should be advanced in the direction of marketing researches, the possibilities of optimum economies of scale and scope economies.
