The paper presents the methodology and implementation of original Automatic CAM programming using machining templates (ACPUT) dedicated to manufacturing special technological tooling. development ACPUT was inspired by observation that although modern computer-aided design (CAD) / (CAM) systems can automatically create programs, their universality makes them both difficult use inefficient becaus...

This study deals with modeling of production risk by means of a two-step procedure. In contrast to earlier studies of production risk, we do not immediately adopt restrictive functional forms for the risky production technology. We first test for the presence of production risk. If production risk is found to be present, the mean and risk functions are estimated separately. This allows the use ...

Multi-objective inventory models of deteriorating items have been developed with vague and imprecise information about available storage area. Here, the objectives are (i) to maximize the profit, (ii) to minimize the wastage cost due to deterioration and (iii) to minimize the total production cost. These objectives are also fuzzy in nature. In these models, production rate is a decision variabl...

walnut is one of the important products in kerman province and baft town is the main area of ‎walnut orchards. so the technical, allocative and economical efficiency of walnut farmers computed ‎assign the degree of farmer’s success in the optimum allocation of their resources. at first the ‎proper production function was estimated, and then stochastic frontier production and technical, ‎efficie...

There is nothing quite so helpless in this world as a baby broiler chick which has been snatched from the warmth of its surrogated mother, carted umpteen kilometers in a box dumped unceremoniously in a broiler shed and then told to get on with the job of making the boss a wealthy man. Yet within the space of 14 days, that same chick, under optimum conditions, will have increased its day-old bod...

Understanding software size distribution is critical to cost estimation using COCOMO model and design of reliable production function model. This paper proposes validates a theoretical framework based on the maximization Shannon entropy learn component systems when partial information about moments given. Specification appropriate moment constraints either in form shifted geometric mean or arit...

In this paper we consider an imperfect production system which produces good and defective items and assume that defective items can be reworked. Due to the nature of rework process we do not restrict the rework rate to be equal to normal production rate or constant and assume that it is a random variable with an arbitrary distribution function. We also assume as it is true in most real world s...

This paper presents sizing, energy management strategy, and cost analysis for a configuration consisting of solar photovoltaic (PV) panels, fuel cell (FC) storage system, and reverse osmosis (RO) desalination technology for combined power and fresh water production. In this system, PV is the main power supply source; fuel cell is a storage system accompanied by Hydrogen production and storage d...

in this paper, the cost and income efficiency models have been considered with regard to the multiple objective programming structures. for finding the efficient points in purposed molp problem, some various methods like lexicography & the weighted sum can be used. so by introducing the molp problem the cost & income efficiencies will be achieved. in the present study, the molp problem ...
