This paper explores the possibility that perishable goods can be ordered several times in a single period after considering the cost of Marginal contribution, Marginal loss, Shortage, and Purchasing under stochastic demand. In order to determine the optimal ordering quantity to improve the traditional newsvendor and maximize the total expected profits, and then sensitivity analysis is taken to realize the influence of the parameters on total expected profits and decision variables respectively. In addition, this paper designed a multi-order computerized system with Monte Carlo method to solve the optimal solution under stochastic demand. Based on numerical examples, this paper verified the feasibility and efficiency of the proposed model. Finally, several specific conclusions are drawn for practical applications and future studies.

The objective of this article is to examine the absorptive capacity in the technology industry and aspires to recognize how firms can manage their strategic decisions in the turbulence contexts. In particular, we examine how organizations can strengthen their organizational contexts in order to absorb knowledge. From the knowledge management literature, this investigation extends our perception of the relationship between the human capital profiles (organization, research and development unit, and recent incorporations) and technological decision-making. Through the SEPI Foundation, a balanced panel of 1,220 Spanish industrial companies has used that answer to the Survey of Business Strategies (SBS) for a threeyear period, which signifies a total of 3,660 cases. The principal finding is the presence of high levels of human resources to understand a decision efficiency process. It also highlights its relationship to the firm’s technological committee. These contributions are notable for both researchers and practitioners. It could be stimulating to expand the study to the association between human capital profiles and other strategic technological decisions, as the preparation of an innovation plan or the measurement of innovation performance.

Companies around the world are under pressure to reduce their prices to be competitive. In order to keep profitability, they are adopting lean manufacturing (LM) and its tools to reduce waste and, consequently, the costs. Value stream mapping (VSM) is an efficient LM tool, identifying production flow waste. When it is possible to combine VSM with other LM tool, such as Kanban, a substantial impact in inventory reduction is reached. Additionally, the conventional account system shows limitations in the costs reduction to keep up with LM. The purpose of this paper is to present the results obtained by the application of the VSM combined with Kanban and the new account approach to measure the effectiveness of the cost reduction in the finished goods inventory. Considering that LM tools application in the textile segment has not an expressive number of researches, four hypothesis are presented and validated. The findings are discussed and finally, the research limitations and the practical implications originated by this work are presented as well as topics for further researches are suggested.

The upcoming logistic environment is about to modify deeply the way we supply products. In fact, some new trends are going to require more and more agility between a large number of stakeholders in open and dynamic networks. This should be possible to achieve thanks to new data collection and treatment abilities. Considering this moving technological and logistic environment, it appears necessary to define and categorize more specifically the main disruptive events that can affect a supply chain. In fact, amount of data are collected on the field and must be helpful to make relevant decisions in case of disruption. In order to understand automatically what these data mean, it is necessary to detect and classify the disruptive events in order to find the best adaptation. This paper focuses on the sensitive products’ supply chains, that are facing with agility high requirements, based on their ability to detect disruptive events. We take as an example the blood supply chain.

In this paper, we study the impact of the Capability Maturity Model Integration (CMMI) on firm performance both during and after its implementation. The literature pointed out that CMMI is theoretically related to the generation of dynamic capabilities. To give an empirical view of these theories, we built a database of economic and financial data from Spanish firms involved in programming, consultancy or another computer-related sector. This data allowed us to study the relationship between the use of CMMI and the firm economic and financial performance in an empirical way. The main finding of the analysis is a negative relationship between the use of CMMI and profitability in the firms during the analyzed period and sector.

This paper illustrates current challenges and suggests solutions within the area of scheduling in the baking industry. The analysis applies the product wheel heuristic approach of King (2009) and tests the production cycles generated using actual sales and production data from a manufacturer of frozen baked goods. The product wheel method showed to be a suitable method for application at the baked goods manufacturer and generated a 23% reduction in setup and inventory cost at the case company. Despite the benefits, the product wheel method proved difficult to apply in a high variety setting, where an operations research model may have achieved more significant results.
