This paper develops Order Acceptance for an Integrated Production-Distribution Problem in which Batch Delivery is implemented. The aim of this problem is to coordinate: (1) rejecting some of the orders (2) production scheduling of the accepted orders and (3) batch delivery to maximize Total Net Profit. A Mixed Integer Programming is proposed for the problem. In addition, a hybrid meta-heuristic...

Thermal cracking of a heavy liquid hydrocarbon was performed in a laboratory scale tubular reactor. Central Composite Design (CCD), was used as an experimental design method. The design variables were Coil Outlet Temperature (COT), feed flow and rate steam ratio. Maximum yield of ethylene was 30.37 wt% at COT, residence time and steam ratio of 869oC, 0.208 s and 1.22 g/g, respect...

    Strategic programming, Complex supply chain, Lean, Production programming, Suppliers selection,   ELECTRE This paper represents a model of strategic programming with limited resources in a complex supply chain. The main goal of the proposed model is to increase efficiency and effectiveness of the supply chain with respect to income increases and cost decreases. Using special objective funct...

according to the vital role of pharmaceutical industry in health care system, pharmaceutical supply chain security, standard production and distribution of the pharmaceutical products are of great importance for pharmaceutical companies. therefore, applying technology, especially radio frequency identification (rfid), is essential to achieve these goals. moreover, due to the importance of secur...

background: sustainable and commercial production of taxol as an anti cancer drug is a critical point to its clinical application. nowadays, hazel because of rapid growth and wide range distribution is considered as an alternative source of taxol. objective: to increase taxol production the cdna encoding 3-hydroxy-3-methylglutaryl-coa reductase (hmgr) from iranian hazel (genebank accession numb...

Proper planning of assembly lines is one of the production managers’ concerns at the tactical level so that it would be possible to use the machine capacity, reduce operating costs and deliver customer orders on time. The lack of an efficient method in balancing assembly line can create threatening problems for manufacturing organizations. The use of assembly line balancing methods cannot balan...

the current status and distribution of the dragonflies (anisoptera) of pakistan were studied during 2005-2009. two dragonfly species were identified for the first time from pakistan. among these, rhodothemis rufa is a red, medium-sized dragonfly. lamelligomphus biforceps is also reported for the first time from pakistan and re-described owing to having minor taxonomic differences from that of f...

this research aims to apply a model to the study and analysis of environmental and natural resource costs created in supply chains of goods and services produced in thailand, and propose indicators for environmental problem management, caused by goods and services production, based on concepts of sustainable production and consumer behavior. the research showed that the highest environmental co...
