Written in English

In this thesis, we obtain the exact steady-state distribution of the number of customers in a GI/G/1 make-to-stock queue, therefore we observe the impact of production time variability on optimal inventory control policies. We also shed light on how system performance deteriorates more because of production stoppages and variability in repair times.We also analyze a production/inventory producing different products. We compare the performances of different scheduling policies in regard of the inventory control parameters and average system costs which are obtained by using the exact steady-state distribution of the number of customers for each static policy (first-come-first-served, preemptive and non-preemptive priority disciplines). We provide the inequalities indicating when it is optimal to switch from make-to-stock to make-to-order policy. We extend the application area of a well-known dynamic scheduling heuristic, Myopic( T), for systems with non-exponential service times. We additionally analyze inventory pooling problem in the M/G/1 make-to-stock queue.

Analyzing make-to-stock queues. In particular, the asymptotic analysis of the inventory aspect of the system is novel.

Other than appearing in two classical textbooks Morse () and Zipkin (), the multi-server make-to-stock queue as a tool for supply chain analysis has received no attention in. Motivated by make-to-stock production systems, we consider a scheduling problem for a single server queue that can process a variety of different job classes.

After jobs are processed, they enter a Cited by: In this paper, we analyse a production/inventory system modelled as an M/G/1 make-to-stock queue producing different products requiring different and general production menards.club: Apurva Jain.

Two queues are fed by independent, time-homogeneous Poisson arrival processes. One server is available to handle both. All service durations, in both queues, are drawn independently from the same distribution. A setup time is incurred whenever the server moves (switches) from one queue to the other.

We prove that in order to minimize the sum of discounted setup charges and holdings costs Cited by: Waiting Lines and Queuing Theory Models Introduction Queuing theory is the study of waiting lines.

It is one of the oldest and most widely used quantitative analysis techniques. Waiting lines are an everyday occurrence for most people. Queues form in business process as well. Mar 11,  · We consider joint capacity–inventory management for multi-server make-to-stock queues operating under a base stock policy.

The number of servers corresponds to the capacity decision, and the base stock level is the inventory decision. Our goal is to minimize a combination of capacity, inventory, and backordering costs. We develop a square-root rule for the joint decision and justify the rule Cited by: 2.

The number of servers corresponds to the capacity decision, and the base stock level is the inventory decision. Our goal is to minimize a combination of capacity, inventory, and backordering costs. In this paper, we study the production time allocation issue for a multi-purpose manufacturing facility.

This production facility can produce different types of make-to-order and make-to-stock products. Using a vacation queueing model, we develop a set of quantitative performance measures for a two-parameter time allocation policy. Based on the renewal cycle analysis, we derive an average cost Cited by: 2.

For make-to-stock products, it is the length of time between the release of an order to the production process and receipt into inventory. Included here are order preparation time, queue time, setup time, run time, move time, inspection time, and put-away time.

Downloadable. We model an isolated portion of a competitive supply chain as a M/M/1 make-to-stock queue. The retailer carries finished goods inventory to service a Poisson demand process, and specifies a policy for replenishing his inventory from an upstream supplier.

The supplier chooses the service rate, i.e., the capacity of his manufacturing facility, which behaves as a single-server queue. Jul 12,  · We analyze the double queue that arises when arriving customers simultaneously place two demands handled independently by two servers.

It is assumed that the customer arrivals form a Poisson process with mean 1, the servers have exponential service times with rates $\alpha,\beta$ and \$1. We consider bi-criteria scheduling problems for three queueing systems (a single queue, a two-station closed network, and a two-station network with controllable inputs) populated by various customer Cited by: 1.

capacitated systems where replenishment lead times are not constant and depend on the congestion in the system. For capacitated systems under continuous review, Buzacott and Shanthikumar () consider an M/M/1 make-to-stock queue and investigate the effects of ADI with constant customer order lead times.

Jan 15,  · JIT is a stock replenishment policy that aims to reduce final product stocks and work-in-process (WIP); it coordinates requirements and replenishments in order to minimize stock-buffer needs, and it has reversed the old make-to-stock production approach, leading most companies to adopt "pull” instead of “push” policies to manage material.

The theory of constraints (TOC) is an overall management philosophy introduced by Eliyahu M. Goldratt in his book titled The Goal, that is geared to help organizations continually achieve their goals.

Goldratt adapted the concept to project management with his book Critical Chain, published in J. George Shanthikumar Richard E.

Keilson, D. Nakazato, H. Zhang), Journal of Applied Probability, 28,This book develops a modeling framework to analyze the problem of inventory management with alternative delivery times.

The general context considered here is that a seller replenishes its inventory in fixed intervals and, between replenishments, allocates the limited inventory to satisfy customers who are both price and delivery-time sensitive. Today’s manufacturing system operations are becoming increasingly complex.

Advanced knowledge of best practices for treating these problems is not always well known. The purpose of the book is to create a foundation for the development of stochastic models and their analysis in.
