Using Environmental Kuznets Curve theory, this article examines the EKC effect of economic growth, energy intensity and carbon emission intensity on total quantity of carbon emission under the constraint of energy-saving policy. Optimizing energy-consuming structure and decreasing energy-consuming intensity can incline carbon emissions intensity and slow down the increasing speed of carbon emis...

We present an extension to the multi-product newsvendor problem by incorporating the retailer’s pricing decision as well as considering supplier quantity discount. The objective is to maximize the expected profit of the retailer through jointly determining the ordering quantities and selling prices for the products, subject to multiple capacity constraints. We formulate the problem as a General...

A dynamic model is presented of a household’s joint production, storage, and trade decisions under price risk, region-wide and idiosyncratic yield risk, and explicit transaction costs. Balancing the goals of profit maximization and hedging against consumption price risk, grain management decisions are nonlinear, interdependent functions of the market price and household grain availability and f...

: This research to determine the policy of controlling raw material inventory in a company if it uses Economic Order Quantity (EOQ) method with current policy. The data used form about main needs and costs incurred ordering storing during 2017-2019. Data collection techniques by examining documents. is descriptive discussion that make systematic picture using object under study. results analysi...

We study a periodic-review inventory model where, in addition to the procurement quantity, price is also a decision variable. We develop a model where demand in each period is a random variable having a priceand, possibly, period-dependent probability distribution, with the expected demand decreasing in price. The model includes price limits and "xed ordering costs in addition to unit procureme...

: This research discusses the design of a spare part inventory control information system in car workshop using Economic Order Quantity (EOQ) method. method functions as an optimization by minimizing and ordering costs, well avoiding excess or shortage inventory. The author designed PHP programming language MySQL database to facilitate website development process. Testing was carried out testin...

NAND flash, used in modern SSDs, is a write-once medium, where each memory cell must be erased prior to writing. The lifetime of an SSD is limited by the number of erasures allowed on each cell. Thus, minimizing erasures is a key objective in SSD design. A promising approach to eliminate erasures and extend SSD lifetime is to use write-once memory (WOM) codes, designed to accommodate additional...

In this paper we study a type of production-inventory system in which the production and demand rates are modulated by a background state process modeled as a finite state Continuous Time Markov Chain (CTMC). When the production rate exceeds the demand rate, the inventory level increases, and when the demand rate exceeds the production rate, it decreases. When the inventory level reaches zero, ...
