Abstract This paper derives the optimal replenishment lot size and shipment policy for an Economic Production Quantity (EPQ) model with multiple deliveries and rework of random defective items. The classic EPQmodel assumes a continuous inventory issuing policy for satisfying demand a...

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...

Our long-term research in process programming is based on the hypothesis that software processes can and should be captured accurately and formally, using executable formalisms to support execution, analysis, and understanding. Many process languages have been developed over the years for modeling processes formally. In this paper, we argue that for automated support, we need not a process mode...

This study digs out some new algebraic properties of an Osborn loop that will help in the future to unveil the mystery behind the middle inner mappings T(x) of an Osborn loop. These new algebraic properties, will open our eyes more to the study of Osborn loops like CC-loops which has received a tremendious attention in this 21st and VD-loops whose study is yet to be explored. In this study, som...

We classify " nice " loop envelopes to Bruck loops of 2-power exponent under the assumption that every nonabelian simple section of G is either passive or isomorphic to PSL2(q), q − 1 ≥ 4 a 2-power. The hypothesis is verified in a separate paper. This paper is a continuation of the work by Aschbacher, Kinyon and Phillips on finite Bruck loops [AKP]. In [BS3] we will apply these results and get ...

The economic production quantity (EPQ) is a commonly used inventory model. An assumption in the EPQ model is that all units produced are perfect. Some researchers have studied the effects after relaxing this assumption on the inventory models. The objective of this paper is to determine the economic production quantity with reduced pricing, rework and reject situations in a single-stage system ...

peripherally inserted venous ports fracture with embolization in patients who received chemotherapy is a serious and rare complication,and few cases have been reported in children. we report a successful endovascular technique using a snare for retrieving broken peripherally inserted venous ports in a child for chemotherapy. catheter fragments may cause complications such as cardiac perforation...

Rework has been and continues to be a problem during the construction of transport mega-projects. This article examines error culture an alliance that forms part mega-project determine its effectiveness in mitigating rework. Our reveals management positively correlates with reducing rework holds divergent relationship aversion culture. We further show negative association between ability reduce...

The research we present in this paper addresses the following question: What type of error culture does rank-and-file workforce experience during construction, and it help mitigate rework? We undertake an exploratory case study Alliance, which forms part a transport mega-project. An questionnaire is administered to Alliance's subcontractors' across four projects. find that management positively...
