Landscape Architecture Planning and Design Based on Landscape Ecology Theory:A Case Study of Waterfront Landscape Planning and Design of Dapo Town

With the rapid development of urbanization,landscape architecture has become an indispensable component of daily life.In order to achieve better landscape effects and protect the ecological environment,landscape ecology theory can be integrated into landscape planning to carry out disciplinary crossing and integration research between landscape ecology and landscape architecture.In this study,based on the basic theories of landscape ecology,the waterfront landscape of Dapo Town was designed,with the aim to achieve ecological balance in planning,showcase biodiversity,and create a harmonious landscape ecological environment which can benefit both nature and people.This design combined artificial and natural elements while improving the natural environment,which promoted a harmonious relationship between humans and nature,thus enriching the spatial organization of the city,and playing a role in regulating the urban environment and climate.

An Architecture of Computer Aided Process Planning System Integrated with Scheduling Using Decision Support System

Process planning and scheduling are two major plann in g and control activities that consume significant part of the lead-time, theref ore all attempts are being made to reduce lead-time by automating them. Compute r Aided Process Planning (CAPP) is a step in this direction. Most of the existin g CAPP systems do not consider scheduling while generating a process plan. Sched uling is done separately after the process plan has been generated and therefore , it is possible that a process plan so generated is either not optimal or feasi ble from scheduling point of view. As process plans are generated without consid eration of job shop status, many problems arise within the manufacturing environ ment. Investigations have shown that 20%～30% of all process plans generated are not valid and have to be altered or suffer production delays when production sta rts. There is thus a major need for integration of scheduling with computer aide d process planning for generating more realistic process plans. In doing so, eff iciency of the manufacturing system as a whole is expected to improve. Decision support system performs many functions such as selection of machine too ls, cutting tools, sequencing of operations, determination of optimum cutting pa rameters and checking availability of machine tool before allocating any operati on to a machine tool. The process of transforming component data, process capabi lity and decision rules into computer readable format is still a major obstacle. This paper proposes architecture of a system, which integrates computer aided p rocess-planning system with scheduling using decision support system. A decisio n support system can be defined as " an interactive system that provides the use rs with easy access to decision models in order to support semi-structured or u nstructured decision making tasks".

APPROACH TO INTEGRATED PROCESS PLANNING SYSTEM ARCHITECTURE

A series of researches on process planning system architecture is described.The definition of process planning in CIMS, a unified description for work procedure of various CAPP systems,including retneval,variant and generative systems,and the information models about part, manufacturing facility are provided to form scientific basis for process planning automation where a Part Model based on Feature and a Production Environment Model based on Work-Element are to be important supports for implementation of the integrated process planning system.These concepts are applied to the development of a prototype system SIP,which is suitable for box-type mechanical parts and consists of three subsystems:CAD,CAPP and NCP.They are linked together by neutral files as interfaces. This is a successfol implementation for engineering integration.

Preliminary Study on Landscape Architecture Safety

In view of the current poor safety consciousness in landscape architecture industry, this paper proposed the concept of landscape architecture safety, and analyzed its characteristics; explored the monitoring means of landscape architecture safety and prevention measures from the perspectives of landscape architecture planning and design safety, landscaping construction safety; and put forward specific schemes from the perspectives of evaluation standards, legal system, and propaganda and education of landscape architecture safety, in order to meet the increasingly urgent needs of landscape architecture safety,and promote the landscape architecture safety in China.
