Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single computing device is used for warehouse scheduling, then device complexity is low, but processing capacity and reliability are insufficient
Solution Approach 1:
The scheduling system is divided into multiple independent computing devices (first computing device, second computing device, etc.), each capable of independently executing scheduling algorithms. This segmentation increases processing capacity and system reliability while maintaining manageable complexity through modular architecture.
Solution Approach 2:
Each computing device is designed with multi-functional capabilities, able to perform various scheduling tasks including receiving order data, determining delivery routes, calculating costs, and communicating with multiple terminals. This universality allows the system to handle diverse scheduling requirements without requiring specialized hardware for each function.
2Loss of information
If detailed scheduling information is provided to all terminals, then information completeness is high, but information security and access control become problematic
Solution Approach 1:
Different terminals are granted different levels of access to scheduling information based on their specific needs and authorization levels. For example, driver terminals receive only route and delivery information, while management terminals access comprehensive scheduling data. This local quality approach ensures information completeness for authorized users while preventing unauthorized access.
Solution Approach 2:
The computing devices act as intermediaries between the central scheduling system and various terminals. They receive comprehensive scheduling information from the system, process it according to terminal-specific authorization levels, and transmit only the appropriate subset of information to each terminal. This intermediary function maintains information security while ensuring each terminal receives necessary data.
3Productivity
If manual scheduling methods are used, then system complexity is low, but time consumption and scheduling accuracy are excessive
Solution Approach 1:
Manual mechanical scheduling operations are replaced with automated computing devices that execute scheduling algorithms. These devices receive order data, automatically determine optimal delivery routes, calculate costs, and generate schedules without human intervention. This substitution dramatically improves scheduling efficiency and accuracy while the modular architecture keeps system complexity manageable.
Solution Approach 2:
The scheduling system is designed to autonomously perform scheduling tasks without requiring manual intervention. Computing devices automatically receive order information, process it through scheduling algorithms, determine routes and costs, and communicate results to relevant terminals. This self-service capability eliminates time-consuming manual scheduling while maintaining system simplicity through automated decision-making processes.
