  • Multi-criteria Decision Based on Safety Requirements in Water Plants

    • Abstract: Multi-criteria Decision Based on Safety Requirements in Water Plants
      Pages 17-22
      Author L. CveticaninS. Opricovi
      In this paper a linguistic multi-criteria method is applied for making decisions in a water plant to provide the safety operation. If the vibration level of pumps is higher than the limit values prescribed by corresponding standards and, besides, the vibration has the tendency to increase, it is necessary to act, but not to perturb the water supply. Alternatives for acting are: to substitute the pump with a new one, to change the bearings, balancing of the pump’s rotor, to rearrange the pumping regime, to fasten the pump construction or to intensify vibration and temperature monitoring of the layers. Which of these actions will be applied depends on the criteria of operation safety, safety of operators, increase of production efficiency, cost of action, in which season of year had happened, is the action necessary and it is necessary to be done instantly. Opinion of experts in field is usually different. The aim of the paper is to give a method for giving the optimal decision due to the mentioned criteria. For these purposes the SofverLingV is developed based on linguistic information. The obtained results agree with those obtained with Software VIKOR which was based on numeric description of the problem by experts. The suggested method is very convenient for application.

  • Exact Controllability of Backward Stochastic Control Systems

    • Abstract: Exact Controllability of Backward Stochastic Control Systems
      Pages 11-16
      Author Xiangrong WangHong Huan
      This paper gives a necessary condition of exact controllability for backward stochastic control systems, and introduces three equivalent conditions of necessary and sufficient for the linear system to be exactly controllable. Finally, as an application of this stochastic control system, two examples on the optimal portfolio problem with consumption will be given.

  • Enhancing the Belief and Self-efficacy of Engineers for Management: An
           Interactive Learning Model

    • Abstract: Enhancing the Belief and Self-efficacy of Engineers for Management: An Interactive Learning Model
      Pages 1-10
      Author Quey-Jen Ye
      Little research considers interactive learning in engineering management. This study proposes a collaborative learning style for engineering workers facing a managerial transition. The examination features three learning opportunities: class lessons, job characteristics, and self-sustaining. A structural equation model serves to test propositions pertaining to their interactive effects based on implicit belief and self-efficacy theories, which stress how beliefs about improvement of managerial abilities mediate between the learning and capability and performance self-efficacies. Tests among 449 engineering workers from Taiwan’s technical firms reveal the significance of this model. Each learning contributes separate advantage: classroom lessons most favoured performance efficacy, job characteristics most favoured improvement beliefs, and self-sustaining favoured competency efficacy the most. Ideally, a combined approach appears even better, and successful outcomes arise for those who can connect their needs with emergent learning opportunities.
