UNLABELLED OBJECTIVES Resource allocation is a challenging issue faced by health policy decisionmakers requiring careful consideration of many factors. Objectives of this study were to identify decision criteria and their frequency reported in the literature on healthcare decisionmaking. METHOD An extensive literature search was performed in Medline and EMBASE to identify articles reportin...

In this study, diamond turning of an aluminiumbased metal matrix composite (MMC) reinforced with SiC particles was conducted with the assistance of ultrasonic vibrations. A simple and small size vibration device was designed to mount a piezoelectric transducer and a diamond insert onto a CNC machine. Turning experiments were carried out using a factorial design to investigate the effects of vib...

The paper deals with ideas of multicriteria decision support with the use of computer based systems. A negotiation problem is considered related to joint realization of a risky innovative project by two parties. It is considered as a multicriteria bargaining problem. A procedure enabling interactive multicriteria analysis and derivation of mediation proposals is proposed. Some results of experi...

A spatial parallel mechanism namely 3-RRS mechanism has been assigned to be attached to the seat of a standard electric wheelchair to prevent the turning over of the handicapped sitting on the wheelchair. The system of the wheelchair and the mechanism is a self-balancing robotic wheelchair and has coped with several road conditions. A stability control system calculates the proper moments on th...

The machining process exhibits piecewise behaviour and cannot be linearly extrapolated in a wide range. It cannot be modelled effectively using theories and equations. Thus, expert systems have emerged as a major tool for decision-making in such complicated situations (Singh & Raman, 1992). The conventional method for selecting machining parameters such as cutting speed and feed rate is based o...

Increasing global demand for travel has drawn public attention to the tourism industry. This industry needs design of intelligent systems based on new concepts facilitate better service delivery. To this end, study proposes a ubiquitous tourist system context-awareness, multicriteria decision making (MCDM), and augmented reality (AR) using geospatial information (GIS). provides two services use...
