We develop the first approximation algorithms with worst-case performance guarantees for periodic-review perishable inventory systems with general product lifetime, for both backlogging and lost-sales models. The demand process can be non-stationary and correlated over time, capturing such features as demand seasonality and forecast updates. The optimal control policy for such systems is notori...

We describe here a case study in compiling a high-resolution forest inventory for central Georgia using the K-nearest neighbor approach with multi-source data and mean balancing correction for the estimation bias. In general, multi-source data collected through various incompatible designs cannot be mixed due to intractable variances and unknown bias. Because of this incompatibility abundant in...

We consider the problem of determining the optimal ordering and reordering policy for an inventory where the entire stockwill simultaneously become obsolete at some (typically random) time, T . Manymanufacturing, publishing, distribution, and high tech businesses face the challenge of maintaining inventories that do not age in the conventional sense; instead, they suddenly become obsolete and l...

Pharmacy managers face unique challenges when it comes to the proper management of inventory, with balancing inventory levels that satisfy patients’ needs while minimizing costs the primary goal. This goal is not met when inventory is managed without careful planning and analysis – for example, just ordering substantial quantities of each formulary medication in an institutional setting. While ...

A Balance between the demand and supply is one of the indicator of the position of your organization in the Market. Every organization tries to match their supply with the demand. However, balancing between the two is highly impossible because of the changing customer requirements. Retail stores whose customer are the end users is very dynamic system as it is prone to the fluctuations immediate...

using the mathematic techniques such as fuzzy approach has useful outcomes for production planning in different sources. in this paper lgp1 was used to model the objectives such as: avoidance of shortage or surplus of demand, access to maximum of income, using the normal capacity of production and organizing the inventory of warehouse, within the framework of goal constraints like balancing be...

optimal balancing is a new approach based on optimal control a which modes, controls and the amount of equilibrium scale are calculated simultaneously. this approach has a significant effect on increasing performance of industrial robots which causes maximum decreasing of energy consumption. despite many applications of robotics such as welding and gluing, the path is predefined , but other unk...
