Diffuse cognitive map was applied to analyse factors of vulnerability to climate variability in rural Andean micro-watershed. The iModeler software was used as a tool that allows the modelling of these maps. As input information, the results of the socioecological dynamics analysis previously implemented in the case study were taken, and weights were assigned to each input factor in relation to a central factor in a time scale. The model applied in the El Chocho micro-watershed - Department of Valle del Cauca in Colombia, can be validated in similar contexts of the Andean Colombian area. A high degree of water shortage and increased pressure on the associated ecosystems was evidenced, which puts at risk the resilience of the socio-ecosystem to face climate variability. The results of this type of models are tools for decision making in adaptation at rural level.

Abstract Background COVID-19 is a highly infectious disease caused by SARS-CoV-2. This article assessed the effectiveness of preventive measures of COVID-19 infection, including social distancing (SD) and quarantine (Q) of patients and contacts in Egypt. Methods A simple model was developed to predict the infection rate without preventive measures. The article utilizes fertile meta- heuristic technique and particle swarm optimization (PSO), to predict the growth of the disease. Results A correlation between the predicted and actual infected cases, validated the proposed forecasting algorithm. Preventive measures together with the Egyptian Government stay home order reduced 98% of expected infections. PSO analyses showed that infection and death rates will continue to increase particularly with lifting these restrictive preventive measures. Conclusions The advised PSO model could predict COVID-19 infection and death rates with high degree of accuracy. This prediction model could help health authorities in decision making.

This paper provides concrete support for business process reengineering (BPR) related decision-making, through analysis of the mechanism of impetus and resistance. We categorize the impetus and resistance according to their domains. We then construct a dynamic model of BPR by using the principles and methods of systems analysis, in conjunction with the theory of mechanical dynamics. On this basis, dynamics analysis of the two forces was carried out and the mechanism of effect was also discussed. In the case study, experimental analysis of BPR in CF Company was carried out with the proposed model. The results showed that the model is applied to analyze the impetus and resistance in BPR as important input into the decision-making for BPR, thus compelling to implement BPR for the enterprise.

In this chapter, we explore social science theories that could explain how executives make decisions in contexts with a high degree of uncertainty. In particular we focus on how emerging young executives respond to risk in situations of uncertainty. First, we conduct a literature review followed by a critical analysis of socio-cultural decision-making literature. Then we performed a controlled experiment using a sample of senior university students to represent young executives. A context of uncertainty was designed which required the participants to work in small teams and make a decision based on incomplete and uncertain information about a managerial case study. In this way, we intended to illustrate what aspects of culture impacts decision making in a context of uncertainty.

 Interests and number of STMIK Balikpapan new student enrollments are increasing every year. The balance of the ratio of lecturers to students is one of the most important components in improving the quality and teaching and learning process of a university. Avoiding shortages in the number of lecturers can be realized by providing scholarship programs to alumni and teaching assistants. This study aims to build a multi criteria decision making application that can assist the Head of HRD in the process of receiving scholarships to advanced and effective study lecturers. The multi criteria decision making application developed in this study uses the SAW method. The implementation of the SAW method includes the process of evaluating the weighting of criteria, evaluating alternative weights, the matrix process, the results of decision making preferences, resulting in the weighting and ranking of each alternative candidate for the scholarship recipient. The results of the evaluation of multi-criteria application decision making in the study are expected to produce modeling with a high degree of accuracy. The results of the analysis carried out can provide alternative recommendations for prospective scholarship recipients to advanced study lecturers in STMIK Balikpapan.

Current supply chain methods are having difficulties in resolving problems arising from the lack of trust in supply chains. The root reason lies in two challenges brought to the traditional mechanism: self-interests of supply chain members and information asymmetry in production processes. Blockchain is a promising technology to address these problems. The key objective of this paper is to present qualitative analysis for blockchain in supply chain as the decision-making framework to implement this new technology. The analysis method used Val IT business case framework, validated by the expert judgements. The further study needs to be elaborated by either the existing organization that use blockchain or assessment by the organization that will use blockchain to improve their supply chain management.
