Activity-based costing (ABC) and the theory of constraints (TOC) represent alternative paradigms for evaluating the economic consequences of production-related decisions. However, their application can lead to contradictory productmix decisions. To resolve this con#ict, it is frequently suggested that the TOC is appropriate for the short run, while ABC is appropriate for the longer term. This p...

Facing new challenges and more uncertainty, manufacturers see the need for flexible solutions and the need to strive to achieve flexibility. However, flexibility is still not well understood and no unambiguous understanding of flexibility exists. The paper first summarizes the state of the field of flexibility, exploring different definitions and understandings of the flexibility concept from t...

This paper builds on prior work examining pedagogical strategies for the teaching of OR/MS. In particular, the authors focus on the use of framing as a pedagogical metaframework and extend the repertoire of frames in use presented elsewhere. The purpose of framing and reframing is to improve the understanding of problems and problematic situations by providing a means of developing and synthesi...

Yogurts are prepared by fermenting milk with bacterial cultures consisting of a mixture of Streptococcus ssp. thermophilus and Lactobacillus delbrueckii ssp. bulgaricus. The main aim of this investigation was to develop a majority goat yogurt, with the addition of sheep milk in order to have a final product with good physicochemical quality properties and sensorial attributes. Four types of yog...

The study was conducted to know the copro-prevalence of hookworm infection in relation to various risk factors in the pet dogs from in and around Ludhiana. Total 250 dog faecal samples were examined by flotation and Mc Master egg counting technique for qualitative and quantitative evaluation, respectively. The prevalence of hookworms was correlated with meteorological data, age, sex and breed. ...

This paper examines firms and the products they manufacture — and abandon — over time. We find strong relationships between product switching and a number of microand macroeconomic variables, including firm performance, aggregate manufacturing growth and product diversification. Most importantly, product switching is a very important — and active — margin of firm adjustment that is positively c...

In this paper, we describe a method for designing flexible mix-product lines. The word "flexible" means product-mix flexibility. Various production plans are executed in the flexible mixed-product line. Therefore, we have to solve problems that have widely expanded search trees to design the flexible mixed-product line, but it's difficult to find optimal answers of large scale design problems. ...

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...
