1 WH一Ⅱ装置设计的约束条件与对策约束条件中等以上城市邮电局,查询台至少配有8个座席,多至16,24,32…座席。设计的计量装置首要条件应具有多路计量能力。其次,各邮电局的现行管理方式,一般采用随机式,即在1日4班轮换制中,话务员每班座席号不固定,上岗和离岗时间也不统一。设计的第2个主要约束条件是能适应这种随机性。 1 WH-Ⅱ Device Design Constraints and Countermeasures Constraints At least above the city’s urban post office, check-in Taiwan with at least eight seats, up to 16,24,32 ... seats. The first condition of the designed metering device should have multiple metering capabilities. Secondly, the current management methods of all post offices generally adopt a random method. In the 4-day shift system on January 1, the operator number of each shift is not fixed, and the posts and departures are not uniform in time. The second major design constraint is to adapt to this randomness.
