The objective of the study was to develop a life cycle assessment (LCA) for pig farming systems that would account for uncertainty and variability in input data and allow systematic environmental impact comparisons between production systems. The environmental impacts of commercial pig production for 2 regions in Canada (Eastern and Western) were compared using a cradle-to-farm gate LCA. These ...

<span lang="EN-US">Planning production is an essential component of the decision-making process, which has a direct bearing on effectiveness systems. This study’s objective to investigate efficiency performance units (DMU) in relation planning issues. However, system manufacturing environment frequently subject uncertain situations, such as demand and labor, this can have effect not only ...

In order to achieve a competitive edge in the market, one of most essential components effective operations management is aggregate production planning, abbreviated as APP. The sources uncertainty discussed APP model include demand, costs, and storage costs. problem usually involves many imprecise, conflicting incommensurable objective functions. application real conditions often inaccurate, be...

Lean manufacturing is a strategic concern for companies which conduct mass production and it has become even more significant for those producing in a project-oriented way by modularization.  In this paper, a bi-objective optimization model is proposed to design and plan a supply chain up to the final assembly centre. The delivery time and the quality in the procurement and low fluctuation of t...
