ABSTRACT
-based collaborative design environment, design resources e more and more varied plex. mon information management systems, design resources can anized in connection with design activities.
A set of activities and resources linked by logic relations can form a task. A task has at least one objective and can be broken down into smaller ones. So a design project can be separated into many subtasks forming a hierarchical structure.
Task Management System (TMS) is designed to break down these tasks and assign certain resources to its task a result of design resources and activities could be managed via this system.
KEY WORDS:Collaborative Design, Task Management System (TMS), Task position, Information Management System
1 Introduction
Along with the rapid upgrade of request for advanced design methods, more and more design tool appeared to support new design methods and forms. Design in a web environment with multi-partners being involved requires a more powerful and efficient management system .Design partners can be located everywhere over with their anizations. They could be mutually independent experts or teams of tens of employees. This article discusses a task management system (TMS) which manages design activities and resources by breaking down design objectives and anizing design resources in connection with the activities.
Comparing mon information management systems (IMS) like product data management system and document management system, TMS can manage the whole design process. It has two tiers which make it much more f1exible in structure.
The 1ower tier consists of mon IMSS and the upper one fulfills logic activity management through controlling a tree-like structure, allocating design resources and making decisions about how to carry out a design project. Its functioning paradigm varies in different projects depend
