In this paper we propose a method that uses corpora where phrases are annotated as Positive, Negative, Objective and Neutral, to achieve new sentiment resources involving words dictionaries with their associated polarity. Our method was created to build sentiment words inventories based on sentisemantic evidences obtained after exploring text with annotated sentiment polarity information. Throu...

For a single product, single-stage capacitated production-inventory model with stochas-tic, periodic (cyclic) demand, we nd the optimal policy and characterize some of its properties. We study the nite-horizon, the discounted innnite-horizon and the innnite-horizon average cases. A simulation based optimization method is provided to compute the optimal parameters. Based on a numerical study, se...

This paper developed integrated production–inventory-marketing models for a two-stage supply chain consisting of one vendor and one buyer. The aim of the paper was to decrease the inconsistency between theory and practice of inventory management by relaxing some unrealistic assumptions such as constant demand and fully perfect items that make the models practically impossible for real-life prob...

A firm facing price dependent stochastic demand aims to maximize its total expected profit over a planning horizon. In addition to the regular unit selling price, the firm can utilize quantity discounts to increase sales. We refer to this dual-pricing strategy as quantity-based price differentiation. At the beginning of each period, the firm needs to make three decisions: replenish the inventor...

The main purpose of this paper is to investigate the optimal retailer’s replenishment decisions for deteriorating items under two levels of trade credit policy to reflect supply chain management situation within the economic production quantity (EPQ) framework. In this paper, it is assumed that the retailer maintains a powerful decision-making right and can obtain the full trade credit offered ...

Urban agriculture is recently being recognized as a distinctive urban land use contributing to greenspaces and food security. The land inventory forms the critical first step in identifying sites for urban agriculture. The authors’ analysis greatly expands on prior land inventory strategies, first analyzing land cover to identify all open areas available for siting urban agriculture. Then in GI...

This work is a contribution to fault propagation analysis in a supply chain network. An event-based fault detection method is applied to fault propagation analysis validation. The goal of this methodology is to discover and validate fault propagation effects on system variables. This knowledge could be used to improve corrective action design in order to compensate negative effects. The methodo...

The original 90-item Creative Behavior Inventory (CBI) was a landmark self-report scale in creativity research, and the 28-item brief form developed nearly 20 years ago continues to be popular measure of everyday creativity. Relatively little is known, however, about psychometric properties this widely used scale. In current we conduct detailed investigation into CBI by applying methods from it...
