This article develops an integrated JIT lot-splitting model for a single supplier and a single buyer. In this model we consider reduction of setup time, and the optimal lot size are obtained due to reduced setup time in the context of joint optimization for both buyer and supplier, under deterministic condition with a single product. Two cases are discussed: Single Delivery (SD) case, and Multi...

We study a variant of the Stochastic Economic Lot Scheduling Problem (SELSP) in which a single production facility must produce several grades to meet random stationary demand for each grade from a common finished-goods (FG) inventory buffer with limited storage capacity. Demand that can not be satisfied directly from inventory is lost. Raw material is always available, and the production facil...

Abstract Today’s industrial transformation is taking advantage of the benefits information and communication technologies (ICT) to evolve into a more decision-making environment in manufacturing. Efficiency, agility, innovation, quality cost savings are goals this one most employed manufacturing processes as case machining. Drilling among last operations different stages machined parts, where a...

In software engineering, it is necessary to consider variables such as quality, effort, productivity, time and cost of development. Those variables are negatively affected when defective artifacts are produced. In this case, the cost of rework to correct defects increases in relation to the time of their discovery. Therefore, initiatives should be undertaken in order to find these defects and c...

This study develops an EPQ model for deteriorating items assuming time and stock dependent demand and time varying holding cost under the effect of inflation in fuzzy environment. Shortages are allowed and partially backlogged. In finding the optimal production quantity, deterioration plays a crucial role in inventory management. Therefore handling of deterioration is in highlight and attracted...

In recent times, in the literature of inventory management there exists a notorious interest production-inventory models focused on imperfect production processes with deterministic time horizon. Nevertheless, it is well-known that high influence and impact caused by learning effect random planning This research work formulates mathematical model for re-workable multi-item system, which demand ...

In this paper, an extended economic production quantity (EPQ) model is investigated, where demand follows a random process. This study is motivated by an industrial case for precision machine assembly in the machinery industry. Both a positive resetup point s and a fixed lot size Q are implemented in this production control policy. To cope with random demand, a resetup point, i.e., the lowest i...

Rework occurs commonly in software development. This paper describes a simple rework example, namely the code refactoring process. We show that contextual information is central to supporting such rework, and we present an artifact provenance support approach that can help developers keep track of previous decisions to improve their effectiveness in rework.
