To gain more competitive advantages and attract more customers from the turbulent business environment, manufacturing firms today must offer a wide variety of products to marketplaces. The existence of component commonality in multi-product fabrication planning enables managers to reevaluate different production design alternatives to lower overall production relevant costs. Motivated by assist...

this paper studies the multi-stage supply chain system (msscm) controlled by the kanban mechanism. in the kanban system, decision making is based on the number of kanbans as well as batch sizes. a kanban mechanism is employed to assist in linking different production processes in a supply chain system in order to implement the scope of just-in-time (jit) philosophy. for a msscm, a mixed-integer...

the article proposes a general subject matter “gender and consumption”, considering the philosophical basis of the subject, and the process involved in constructing a consuming model. the authors believe a consuming model has three related, harmonious stages in production, distribution, and consumption. the formation of consuming is based on foundation of “need production” and it’s relation to ...

We present a gas-liquid microfluidic system as a reactor to obtain magnetite nanoparticles with an excellent degree of control regarding their crystalline phase, shape and size. Several types of microflow approaches were selected to prevent nanomaterial aggregation and to promote homogenous size distribution. The selected reactor consists of a mixer stage aided by ultrasound waves and a reactio...

the first motive for the determination and evaluation of an energy productionsystem is the need to change. such system is dynamic in nature and is influenced bymany factors such as age and physiological status of individual sheep or goat, quantityand quality of available feed and environment including the management systems.traditional pastoral resource assessments do not always account for the...

Problem statement: Traditional scheduling models which only address the sequence of jobs to be processed at the production stage under some criteria are no longer suitable and should be extended to cope with the distribution stage after production. In a rapidly changing environment, competition among enterprises has a tendency to turn towards competing between supply chain systems instead of co...

BACKGROUND Understanding the process of relapse to abused drugs and ultimately developing treatments that can reduce the incidence of relapse remains the primary goal for the study of substance dependence. Therefore, exploring the metabolite characteristics during the relapse stage is valuable. METHODS A heroin self-administered rat model was employed, and analysis of the 1H-nuclear magnetic ...

The objective of this paper is to describe a control technique that can be use in a supply chain environment. A multi-product, multi-stage manufacturing system was built and simulation was used to analyse the system behaviour. System benefits were investigated based on the behaviour of the following performance measures: flow time, lateness, work in progress and production cost.

A number of researches have been made on the productive effect of ICT, including its relationship with corporate structure and business process. However, regarding the relationship between the development stage of ICT application and the productivity, only some conceptual frameworks of development stages had been suggested and no experimental study has been made. In this paper, using the indivi...
