Production planning and maintenance are two important problems in manufacturing systems. Despite the relationship exists between these two problems due to sudden failures and production capacity occupied by maintenance activities, each of these problems planned separately and as a result program and model efficiencies reduce in the real world. The aim of integrated production and maintena...

Assembly plays an important role in any production system as it constitutes a significant portion of the lead time and cost of a product. Virtual computer-integrated manufacturing (VCIM) system is a modern production system being conceptually developed to extend the application of traditional computer-integrated manufacturing (CIM) system to global level. Assembly scheduling in VCIM systems is ...

The basic assumption in the traditional inventory model is that all outputs are perfect items. However, this assumption is too simplistic in the most real-life situations due to a natural phenomenon in a production process. From this it is deduced that the system produces non-perfects items which can be classified into four groups of perfect, imperfect, reworkable defective and non-reworkable d...

in order to evaluate the effect of different sources and rates of nitrogen the growth and biomass production of purslane, a randomized complete block design was conducted with three replications at the agricultural research farm of shahrekord university in 2012. fertilization treatments were consisted of control (no n amendment), 30 and 90 kg n ha-1in the form of urea fertilizer, 30 and 90 kg n...

a comprehensive and integrated study of any supply chain (sc) environment is a vital requirement that can create various advantages for the sc owners. this consideration causes productive managing of the sc through its whole wide components from upstream suppliers to downstream retailers and customers.  on this issue, despite many valuable studies reported in the current literature, considerabl...

Present paper describes major RTD challenges and key technologies in order to respond to the demand for consumer oriented highly flexible and networked production systems. Shoe manufacturing is considered as a pilot sector, and a factory for the production of highly customized footwear is discussed as an example of agile and balanced production system, capable of integrating and cooperating wit...

---------------------------------------------------------------------***--------------------------------------------------------------------Abstract — The aim of my paper is to automate the process of whole assembly plants by contributing for speeding up the production, qualitative and costefficient units. Interfacing IPMS with PLC (Programmable Logic Controller) the automobile manufacturing pl...

The critical importance of integrating production, distribution, and inventory (POI) operations has long been recognized by top management of many companies. Now. using the latest advances in Management Science modeling and solution technology, an integrated computer-based POI system has saved approximately $18 million dollars during its first three years of implementation for a major national ...
