Research On Time Quota Of Spindle Workshop In Shijiazhuang Qiangda Pump Industry

With the gradual rise of multi-variety and small-batch production modes,the man-hour quota management for multi-variety and small-batch production models are not mature enough.In the quota of batch products,there is a large deviation from the actual production operation time so that the product delivery date cannot be expected,which affects the competitiveness of the enterprise products in the market.How to formulate more accurate time quotas is an urgent problem to be solved by multi-variety small-batch production enterprises.The Spindle Workshop in Qiangda Pump Industry are multi-variety and small-batch products,and there are great problems in the current man-hour quota management.In this paper,taking the spindle man-hour quota as the research object,the present situation of the current man-hour quota in the workshop is analyzed so as to find out the main problems.The time for preparation and end,allowed time for organization,allowed time for individual needs and relaxation,hand time and overlap time of machine and hand are measured and determined by the stopwatch method.Using SPSS software to fit the measured data of the spindle machine time of different parameters in the Time quota,to construct the machine time model,and finally obtain the standard time quota of the spindle product;Then,by adopting the law that the operation time of batch new products is gradually reduced with the processing of production,the SPSS software is used to fit the power function of the learning curve,the plan correction coefficient is constructed,and the operation time in the standard time quota of the spindle is corrected to obtain the final Planned time quota for bulk products.By introducing the learning curve theory,the work time in the standard work time quota is modified,and the planned work time quota of batch products is more consistent with the actual production.The production plan is prepared in the main shaft workshop,and the safety period of the product is shortened,the purpose of delivery on schedule is realized,and the competitiveness of the enterprise is improved.
