This research focuses on the use of constrained capacity availability as a managerial decision variable in production systems. A simulation model was used to evaluate production system performance at various levels of constrained capacity before additional incremental levels of capacity were added. The results indicate that as levels of available capacity approach planned demand levels, or as d...

The paper studies the optimal production run length for a deteriorating production system. The optimal warranty cost is determined by a balance between the warranty cost of the manufacturer and the buyer during its warranty period. It is assumed that the elapsed time until the production process shift is age dependent and arbitrarily distributed. The objective is to minimize the total cost per ...

The purpose of this article is to develop a method for short and medium term capacity setting decisions for providing a market oriented level of available capacity for the investigated machine groups. An MTO (make to order) production system is considered. The basic concept is that the cumulative available capacity of the machine group has to be greater than or equal to the cumulative needed ca...

Many processes contribute to the speech production system. Brain damage can lead to a wide variety of disorders of the spontaneous production of sentences. Different symptoms of a sentence construction disorder, such as agrammatic and paragrammatic speech errors, are briefly described. An explicit model of the grammatical processes is proposed, and it is shown how the symptoms can be explained ...

It is expected that residential units may replace   traditional heat and power production systems with cogeneration ones. Among the different cogeneration systems, fuel cell based systems are a suitable choice due to their high efficiency, high power density, low emission and low noise. In this paper, a cogeneration system based on solid oxide fuel cells is examined. The system, including the f...

abstract the aim of this survey is to compare utilization systems (cooperative, private and governmental) methods of energy consumption in soybean production and the evaluation of energy inputs effect in yield of soybean in moghan. for this purpose, the information were collected from 54 private farmers, 14 cooperative members farmers and 14 agro-industry units by questionnaire method. the maxi...

Up to now, production systems only concern was to minimize production costs or optimize the utilization of production resources. But with the increasing energy prices and the growing concern over the environmental impact of production systems (industrial systems consume a quarter of all energy), efficient use of energy in manufacturing environment cannot be ignored any longer. MANUbuilding conc...

This paper describes the specification of requirements and the functionality, of a novel agricultural mechanisation system based on small smart machines. It separates the current mechanisation methods from the original plant requirements and in doing so allows a new specification to develop based on agronomic, economic and environmental needs that can lead to a more sustainable production syste...

Introduction Making N rate recommendations for corn has been one of the most economically important goals of publicly funded crop production and soil fertility personnel and programs over the past five decades. Changes in cropping systems, hybrids, tillage, and other management practices, along with opportunities in site-specific inputs and awareness of the need to minimize the amount of N that...

The paper presents the problems with integration of the companies within the supply chain. Usually the separate actions are undertaken by the companies to implement lean tools for production systems and external logistics processes. This situation leads to minor results or moving the costs between production and logistics processes instead of reduction. The purpose of the paper is to present th...
