One of the most important effective factors in the economic growth is the increased efficiency of manufacturing sectors. Thus, it is necessary to review and measure the efficiency of business units from a variety of dimensions to plan the increase of efficiency in future courses. One of these dimensions is the economics to scale (ES) referring to the concept of enhanced earnings due to the incr...

in this model, we establish an inventory model to determine the optimal inventory replenishment scheme for the economic production quantity (epq) model for imperfect, deteriorating items with sales return service under multiple production and rework setup. in one cycle, production process can produces the products in m production setups and reworks the defective items in one rework setup. the c...

This paper proposes the notion that Mobile Agent Technology can improve the alignment between IT systems and the real world processes they support. This can aid enterprise agility, particularly where distributed information is a feature, as in the virtual enterprise. A model of the manufacturing Sales/Order process is proposed. The sales order is shown to be a naturally mobile element of the mo...

This paper analyzes the effect of public R&D subsidies on firms’ private R&D investment per employee and new product sales in German manufacturing. Parametric and semiparametric two-step selection models are applied to this evaluation problem. The results show that the average treatment effect on the treated firms’ R&D intensity is positive. The estimated effects are robust with respect to the ...

This study develops two extended economic manufacturing quantity (EMQ)-based models with a discontinuous product issuing policy, random machine breakdown, and rework failures. Various real conditions in production processes, end-product delivery, and intra-supply chains such as a producer-retailer integrated scheme are examined. The first model incorporates a discontinuous multi-delivery policy...

We examine the interrelationship between export and domestic sales. Our expectation is that they are simultaneously determined, and as such should not be examined in isolation. We also investigate how firm factors—such as R&D and advertising investments—and external factors—such as market growth and exchange rate changes—impact export and domestic sales. Using a non-recursive system of equation...
