This paper presents an economic production quantity (EPQ) model with a periodic order quantity (POQ) policy, product reliability and periodic demand. The machine reliability has decreased over time; therefore, the rates of perfect and defective products reduce and increase over time, respectively. A fixed percentage of these products are reworked while the rest is wasted. Some equipment in thei...

in this model, we establish an inventory model to determine the optimal inventory replenishment scheme for the economic production quantity (epq) model for imperfect, deteriorating items with sales return service under multiple production and rework setup. in one cycle, production process can produces the products in m production setups and reworks the defective items in one rework setup. the c...

The triple bottom line (TBL) strategy has provided the manufacturers with optimized production systems to achieve their economic, environmental, and social goals simultaneously. This paper presents a multi-objective mixed-integer programming model for sustainable economic quantity (S-EPQ) based on TBL strategy. is optimize total profits, environmental emissions of manufacturing activities, turn...

In general, traditional production-inventory systems are based on a number of simplifying – but somewhat unrealistic – assumptions, including constant demand rate, constant holding cost, and instantaneous order replenishment. These assumptions have been individually challenged in numerous variations of production-inventory models. Finite production rate models, such as economic production quant...

Recently, market globalization and competition have forced companies to find alternative means to boost sales and revenue. The use of the cash flow is increasingly becoming a viable alternative for managers to improve their company’s profitability in a supply chain. In today’s business transactions, a supplier usually asks a manufacturer to pay via the advance-cash-credit (ACC) payment scheme i...

It is well-known that the production-inventory problem for deteriorating items in supply chain a challenge when deciding on how many products to manufacture obtain maximum total profit. This research work develops an economic production quantity model item under partial trade credit policy considering inflation, effect of reliability factor system, and demand depending price product whose selli...

An extended economic production quantity (EPQ) model under stochastic demand is investigated in this paper, where a fixed lot sizing policy is implemented to reduce the complexity of production planning and inventory control, and outsourcing with a secondary facility is used to supplement the lot sizing policy and to cope with the random demand. The considered cost includes: setup cost for the ...

The basic assumption in classical production quantity models is that all of the products produced are free defect. But real life, this not always valid. EPQ were examined for situation where proportion defective a random variable and fits certain probability distribution. When literature reviewed, it seen scanning speed accepted as equal to rate. In study, model was developed under condition sm...

Adequate and reliable lexical resources are essential for effective sentiment analysis and opinion mining. This paper proposes a methodology for the emotional assessment and annotation of words. The process is based on the Self Assessment Manikin test, and is coupled with two psychometric measurements for identifying possible bias due to the annotator's psychological condition and personality: ...
