The present study attempts to establish a framework for computing customer lifetime values company in the auto repair and maintenance industry. value defined this consists of current future customer, which involve an estimation length, purchasing behavior profit associated with each customer. proposed contains three groups techniques obtain these estimates from historical transactions. first group includes logistic regression model decision tree estimate churn probability to, further,...

Abstract This paper derives the optimal replenishment policy for imperfect quality economic manufacturing quantity (EMQ) model with rework and backlogging. The classic EMQ assumes that all items produced are of perfect quality. However, in real‐life settings, generation is almost inevitable. In this study, a random defective rate assumed. All inspected classified as scrap repairable. A process involved each production run when regular ends, failure repair also Unit disposal cost unit...

This paper derives the optimal replenishment lot size and shipment policy for an Economic Production Quantity (EPQ) model with multiple deliveries rework of random defective items. The classic EPQ assumes a continuous inventory issuing satisfying demand perfect quality all items produced. However, in real life vendor–buyer integrated system, multi-shipment is practically used lieu generation inevitable. It assumed that imperfect fall into two groups: scrap rework-able Failure repair exists,...

In a recent paper, Chiu et al. (2014) utilized mathematical modeling and differential calculus to determine the common production cycle time that minimizes total production, inventory, delivery costs for multi-item economic quantity (EPQ) model with scrap, rework, multi-delivery. The present study proposes an algebraic approach substituting use of on system cost function deriving optimal in aforementioned EPQ model. This simplified may enable managing practitioners resolve real models more...

This study uses an alternative fabrication scheme to the effect of rework nonconforming items and delayed differentiation on a multiproduct supply-chain system.Traditional economic production quantity model focuses single-product inventory system where all products made are assumed be perfect quality finished issued continuously.To increase machine utilization, lower costs in production, reflect real-world vendor-buyer integrated systems Chiu et al. (2016a) [

This article studies the optimal replenishment policy for an economic manufacturing quantity (EMQ) model with failure in rework, backlogging and random breakdown. A recent [P.A. Hayek M.K. Salameh, Prod. Plann. Control 2001;12:584–590] investigated lot size problem on imperfect quality EMQ model. However, most real-life systems breakdown is another inevitable reliability factor. To cope stochastic machine failures, production planners need to calculate mean time between failures establish a...

This paper is concerned with determining the optimal common production cycle policy for a multi-item economicproduction quantity (EPQ) model scrap, rework and multiple deliveries. The classic EPQ considers theoptimal replenishment of single product under perfect assumption continuous inventoryissuing policy. However, in real life planning, manufacturing firms often plan to have productsmade turn on machine order maximize utilization. Also, dealing random defectiveitems during run seems be an...

This study explores a finite production rate (FPR) model featuring overtime option and rework of nonconforming products. Classic FPR assumed all items produced are perfect quality. However, in real fabrication systems, owing to diverse uncontrollable conditions, is inevitable. To maintain high product quality lower cost allow present-day's manufacturing firms gain competition advantage. Also, due limited in-house capacity, be able smooth schedule enables management meet dates better allocate...

Facing harsh competition in global marketplaces, management must construct the best possible supply chains to meet client requirements of quality, timely, and diverse products. To accelerate fabrication rate can help shorten length refilling cycle, reworking repairable defectives retain requisite quality standard as well reduce cost production. Seeking build an integrated fabrication-delivery model satisfy timely multiproduct needs with goods minimum cost, this study explores a multi-item...

In a turbulent and highly competitive business environment, management always pursues options to reduce overall operating costs.The vendor-buyer integrated system has recently drawn attention from managers, because it can benefit both parties of the supply chain is suitable be applied so-called intra-supply within present-day globalized enterprise.This study attempts simultaneously determine production shipment decisions for multi-product inventory with rework process, wherein multiple...

This study explores the effect of delayed differentiation on a multiproduct vendor-buyer integrated inventory system with rework to identify its potential benefits and provide managers in-depth information for operational decision-making.The main considerations proposed include fabrication plan increase machine utilization, process ensure product quality, multi-shipment policy distribute end products.In addition, these products sharing an intermediate part which two-stage scheme is adopted,...
