The Application of Constraint Satisfaction Technique in Conflict Detection and Resolution

The conflict detection and resolution in collaborative design is a key issue to maintain multi disciplinary design consistency. This paper proposes a new method for conflict detection and resolution based on constraint satisfaction technique. The representation of design constraint, the interval arithmetic of the constraint satisfaction problem CSP and the conflict resolution strategy based on constraint relaxation and adjustment are introduced. A constraint satisfaction based conflict detection and resolution tool CSCDR is then developed. It can help collaborative designers to detect and resolve the conflicts in time in the early stage of the design process so that the unnecessary design iteration and repeated negotiation are avoided and the design efficiency is then much improved. A design case illustrates the effectiveness of CSCDR.

美国辐射呼机^R和辐射呼机^R-S

美国探测技术工程公司生产的辐射呼机^R和辐射呼机^R-S是手持式辐射探测器，其大小与普通呼机相似，可别在腰带上或放在衣袋内使用。就其体积而言，该辐射呼机是目前市场上最灵敏的辐射探测装置。辐射呼机之所以小而灵敏。
