We model an isolated portion of a competitive supply chain as a M/M/1 make-tostock 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., capacity, of his manufacturing facility, which behaves as a single-server queue with exponential s...

We consider stochastic nite-horizon inventory models with discrete distributions that are incompletely speciied by selected moments, percentiles, or a combination of moments and per-centiles. The objective is to determine an inventory policy that minimizes the maximum expected cost over the class of demand distributions satisfying the speciications described above. We show that many inventory m...

Standing inventory analysis allows a forester to predict the yield (volume by logtype) of a section of forest before the trees have been felled. Current standing inventory tools such as MARVL and ATLAS Cruiser predict yield. They do this by simulating the bucking that will take place when the trees are harvested. These tools produce a point estimate of the yield for given input data. In practic...

This paper deals with the sensitivity analysis (SA) of inventory management models when uncertainty in the input parameters is given full consideration. We make use of Sobol’ function and variance decomposition method for determining the most influential parameters on the model output. We first illustrate the method by means of an analytical example. We provide the expression of the global impo...

Retail inventory productivity is of considerable interest to retailers, manufacturers and distributors who service them, and stock market analysts. Inventory turnover is frequently used to measure inventory productivity. We find wide variation in inventory turnover across retailers and over time. The causes of this variation have not been studied systematically to our knowledge. We develop a lo...

Towards Small-footprint Airborne LiDAR-assisted Large Scale Operational Forest Inventory -A case study of integrating LiDAR data into Forest Inventory and Analysis in Kenai Peninsula, Alaska

goal: the current study was performed in order to construct and normalize the marital commitment inventory amongst the students of iran’s state universities. method: this is a descriptive research. the inventory was constructed via delphi technique based on johnson’s theoretical framework. it had 37 items and 2 additional items for detecting lies. in this way 500 persons were selected from the ...

Based on the real-world inventory control problem of a capacitated healthcare apparel service centre in Hong Kong which provides tailor-made apparel-making services for the elderly and disabled people, this paper studies a partial backordered continuous review inventory control problem in which the product demand follows a Poisson process with a constant lead time. The system is controlled by a...

In this paper, we attempt to develop an inventory model for deteriorating items with the consideration of the fact that the use of preservation technology (PT) can reduce the deterioration rate significantly. In this model the shortages are allowed and salvage value is incorporated to the deteriorated items. Demand rate is constant, deterioration rate is time dependent with Weibull’s distributi...
