To implement CONWIP control in multiproduct systems, planners must specify not only a total WIP level, but also its allocation to the different products. We describe two methods for setting individual product WIP levels. The first approach focuses on equitably meeting randomly arriving orders for the various products. We designed a heuristic allocation procedure to attain a throughput target. T...

Introduction: Increasing pressure on available funds in health care section especially hospitals, enhances the need of analyzing different strategies in economic terms. One of the solutions for the optimal use of financial resources and potentials in hospitals and health care centers is using elements of the marketing mix. In this way we could make the best use of the resources...

Firms' decisions about which goods to produce are often made at a more disaggregate level than the data observed by empirical researchers. When products differ according to production technique or the way in which they enter demand, this data aggregation problem introduces a bias into standard measures of firm productivity. We develop a theoretical model of heterogeneous firms endogenously self...

Several types of regulations limit the amount of different emissions that a firm may create from its production processes. Depending on the emission, these regulations could include threshold values, penalties and taxes, and/or emission allowances that can be traded. However, many firms try to comply with these regulations without a systematic plan, often leading not only to emission violations...

In a recent and ongoing work, Baldwin and Klemperer found a connection between tropical geometry and economics. They gave a sufficient condition for the existence of competitive equilibrium in product-mix auctions of indivisible goods. This result, which we call the Unimodularity Theorem, can also be traced back to the work of Danilov, Koshevoy, and Murota. We introduce auction theory for a mat...

business and its main functions such as marketing has value regulations in islamic economy. the main purpose of this paper is the indicatation of islamic values in marketing mix decisions. to achieve this purpose , the islamic values in marketing mix decisions include product, price, promotion and place decisions emanated from quran and documented practices of the holy prophet (peace be upon hi...

We propose a hybrid procedure based on Bounded Dynamic Programming assisted by linear programming to solve the Mixed-Model Sequencing Problem with Workload Minimization, with serial workstations, free interruption of the operations and with production mix restrictions. We performed a computational experiment with 7 instances from a case study related to the Nissan Powertrain plant located in Ba...

Yoghurt is a unique fermented dairy product, consumed throughout the world and the trend ofconsumption is increasing due to its unique health benefits. Yoghurt mix is often supplemented with MSNF(milk solids-non-fat), it may contain as much as 5.7% unhydrolysed lactose. Lactose can be hydrolysed withan enzyme lactase. Deficiency of lactase in lactose-intolerant persons leads to gastrointestinal...

For mixed-model production lines, this paper proposes a production control system based on lean and agile strategies for responding to changes in product mix is proposed. Performance of the proposed system under the conditions of unstable changes in product-mix is analyzed by simulation experiments, and it can be claimed that the proposed system can respond to changes in product mix by re-alloc...

This paper re-explores the relation between a country’s level of wealth and the mix of products it exports. It shows how a country’s capabilities i.e., its productivity and quality levels in each good, simultaneously determines both the mix of goods it produces and exports, and its level of gdp per capita. In our multi-product general equilibrium setting, the relation between a country’s qualit...
