The PSP (Personal Software Process) is a set of practices aimed at time management and personal productivity improvement, applied primarily within software engineering tasks. These techniques can be exploited in order to improve the management of tasks both managers for decision-making and employees of software development companies. In this paper is presented different experiences during the application of the most basic practices of this process, presenting its impact results in the planning of the agenda management tasks such as software development projects for the development team.

A Data Warehouse (DW) is a data repository containing data from different sources. It is used to support decision-making through data analysis as it allows quantitative indicators such as amounts. However, data analysis lack of data of diffuse nature. For instance, in an academic context, the answer to the query "What students scored with good final grade" cannot be obtained from a traditional DW because they do not handle qualitative information. Due to the limitations of traditional DW the use of fuzzy logic may extend its capabilities through a fuzzy DW (FDW). This paper presents an implementation of FDW aimed at allowing qualitative analysis of scholar data supporting decision making process. The FDW implemented operate fuzzy measures, fuzzy facts, fuzzy relations and fuzzy levels. [ABSTRACT FROM AUTHOR]

The links between knowledge, information and decision making in tourism industry have been addressed mainly at the level of tourist destinations, however there have been described deficiencies in the study of these relationships at the level of business organizations that interact in those destinations. The fact is shown in the weak production of academic articles that help to explain the decision-making and knowledge management in these entities, where although its importance is recognized there are factors that affect the development and implementation of both processes such as the lack of systemic approaches, models and methodologies. In this paper a theoretical analysis of the research topics is done, showing its evolution and current trends, which supported the development of a conceptual framework, and dimensions from which a procedure is proposed to study the alignment of decision making with knowledge management in business organizations related to tourism. The procedure is applied in entities placed on Holguin Tourist Destination located to the east of Cuba. [ABSTRACT FROM AUTHOR]

In this paper, a simultaneous use of simulation and optimization techniques for the logistic operation planning is presented, specifically aimed to support the decision making processes related with fleet size determination in the supply--distribution process. The study is developed for a Cuban company dedicated to the transportation of goods and warehousing services. The implementation of the proposed tools enabled suggesting the optimal number of trucks to be used, considering minimization of the idle time of trucks and maximization of the customer service level. Experimental results show a significant improvement regarding the lead time reduction and the increment of order fulfillment for the customers of the company. [ABSTRACT FROM AUTHOR]

In a highly dynamic world, due to technological, economic, political and social changes in the environment, it has been recognized that the production systems play a critical role in the competitiveness of an organization. In this research the authors propose the integration of lean thinking in managing a production system using the technique of discrete event simulation using Petri nets as the support methodology in the process of decision making. Decision making in a lean production system is a complex process because it has static (structural) and dynamic (operational) characteristics and a set of waste presented in it. This paper presents the design of a set of structures that represent different stages in a production process of tires and that is it possible to prove that the design of a model, using the methodology of Petri nets, helps to have an effective and efficient decision making for waste disposal, this thanks to the properties of such nets to model discrete events and analyse the dynamic behaviour of the system. Finally the simulation allows analysing a set of parameters through a systemic indicator OEE (Overall Equipment Efficiency) and demonstrate that the implementation of methods, techniques and tools proposed in the lean production theory generate synergy in the system.
