An AHP-based approach to PMISs assessment
The project management environment gets complex and subject to uncertainty. The firm's managers need of tools supporting the decision–making process in order to properly manage project information. PMISs provide features facilitating the project management. The variety of software and the ambiguity of features meaning make the choice of the PMIS a difficult task. The literature analysis confirms the importance of user engagement in features and PMIS assessment and the lack of methodologies satisfying such a task. The paper focuses on the classification and assessment of features of PMIS considering the firm's needs. A case study is presented for the evaluation of a PMISs sample.
La shelf life per la gestione delle scorte
An expert system for vineyard management based upon pervasive computer technologies
Determining the optimal maturity level for performing viticulture operations and harvesting activities is a difficult task, because, depending on the variety, the climatic conditions and cultural practices, the phenologic maturation process occurs at different times. Recently, ubiquitous computing technologies allow an extremely precise and cost effective monitoring of environmental conditions by means of an RFID based sensor networks. The implementation of such technologies in vineyard management is nowadays under development, however, besides the possibility of gathering data, the need is perceived of developing decision support tools to fully exploit the potential opportunities of these …
Alternatives to the traditional waste management: Food recovery for human non-profit organizations
Food supply chains are affected by losses of products which become poorly attractive for the consumers as they get close to their expiration date, therefore remaining unsold on the shelves. Such situation is ethically depreciable considering that many undernourished people rely on non-profit organizations for their survival. Despite of this situation, food recovery through the supply chain is still scarcely practiced, and the potential benefits achievable are frequently ignored. The paper presents a mathematical model for the coordination of the supply chain operating a food recovery policy. The model determines the optimal time for withdrawing the products from the shelves and the quantity…
Design, development and validation of a system for automatic help to medical text understanding
Abstract Objective The paper presents a web-based application, SIMPLE, that facilitates medical text comprehension by identifying the health-related terms of a medical text and providing the corresponding consumer terms and explanations. Background The comprehension of a medical text is often a difficult task for laypeople because it requires semantic abilities that can differ from a person to another, depending on his/her health-literacy level. Some systems have been developed for facilitating the comprehension of medical texts through text simplification, either syntactical or lexical. The ones dealing with lexical simplification usually replace the original text and do not provide additi…
Application of multi-criteria decision making to PMISs assessment
This paper builds on a previous study concerning the assessment and ranking of Project Management Information Systems (PMISs) features and the comparison of a PMISs software sample. In such an application a Multi-Criteria Decision Making (MCDM) tool such as the Analytic Hierarchy Process (AHP) was adopted to get the ranking by neglecting the mutual influence of elements within the structure. The present paper aims at taking into account such influences by relying on the Analytic Network Process (ANP) for the assessment and ranking of features, while the PMISs software assessment has been performed through the AHP via the direct assessment.
Decision models enabling the supply chain optimization
The expected value of the traceability information
Abstract Recent regulations on agri-food traceability prescribe traceability throughout the entire supply chain, in order to ensure consumers’ safety and product quality. This has led producers and retailers to consider the opportunity to improve the firm's reputation and consumer confidence through the implementation of traceability systems designed not only to satisfy the legal requirements, but also to track the quality of the products through the supply chain for optimization purposes. However the actual implementation of such systems depends on the possibility of gathering specific information related to the product quality. Nowadays, innovative and non invasive technologies such as th…
Sviluppo di modelli decisionali per la supply chain di prodotti deperibili mediante l’applicazione di tecnologie innovative
The supply chain of perishable products, as fruits and vegetables is affected by environmental abuses from harvest to the final destination which are responsible the uncontrolled deterioration of food. In order to reduce such phenomena the supply chain members should control and monitor the conditions of goods in order to ensure their quality for consumers and to comply with all legal requirements (Garcia Ruiz, 2008). The most important factor influencing the food quality is the temperature able to prolonging the shelf life of the products. Since the temperature can inhibit or promote the maturation and deterioration process, this parameter is involved both in the growing process of fruits …
CROSS-DOCKING TRANSSHIPMENT PROBLEM APPROACHED BY NON LINEAR PROGRAMMING AND SIMULATION ANALYSIS
The need for fast product delivery causes the attention of supply chain is addressed to strategies able to optimize the distribution process. In this field the crossdocking seems to be an efficient strategy which makes possible to reduce or eliminate the storage phase by meeting customer demand. In this paper a transshipment problem for cross-docking strategy is considered by means of a deterministic model studied through the non linear programming technique. The solution found allows to determine the optimal quantities to ship, the number of routes activated and the optimal truck number when the constraint on truck capacity is enforced. The influence of the demand fluctuation is also addre…
An expert system for vineyard management based upon ubiquitous network technologies
Vineyard operations for quality wines production are currently based upon costly and time-consuming manual sampling operations required to assess the maturity phases of grapevines. The ripening process however is significantly influenced by the environmental parameters which nowadays can be effectively monitored by means of ubiquitous computing technologies. Besides the possibility of gathering data, hence, suitable tools are required to support the vineyard management process. The present research concerns the development of an expert system to effectively manage the vineyard operations. The methodology is based on the analysis of the time series of indices related to the maturation phases…
ANALYSIS OF A WAREHOUSE MANAGEMENT SYSTEM BY MEANS OF SIMULATION EXPERIMENTS
The supply chains for perishable products are nowadays affected by significant wastes and losses. Their management hence requires optimized approaches in order to remove such inefficiencies. In particular optimized warehouse management policies is a well established research topic which has been recently enriched with specific formulations for deteriorating stocks and shelf life based picking rules. In such context the proposed research aims at investigating the optimal warehouse management policy, taking into account the effects of uncertainty by means of simulation and approaching the effect of optimal picking rules. In the proposed approach, on the basis of a Weibull deterioration proces…
