具体实施方式 Detailed ways
图1是本发明生产计划自动排程系统较佳实施例的硬件架构图。该系统主要包括主机10及与主机10相连接的数据库30。FIG. 1 is a hardware architecture diagram of a preferred embodiment of the production planning automatic scheduling system of the present invention. The system mainly includes a
数据库30储存有订单资料、已经开始投入生产的货物情况(work in process,WIP)、生产线上各工站的产能排配情况、月出货需求计划表及物料进厂计划表等资料。其中,订单资料包括各订单的交期、客户、订单货物的种类,订单需求的数量、完成一个订单所涉及的任务(投料、裁切、背胶贴合、……装配、入库)、各任务需经过的工站、任务经过工站的顺序等信息。产能是指生产设备在一定的时间内所能生产的产品数量。各工站的产能排配情况包括各工站的平均产能、最大产能,各工站包含的机台数量,每个机台的固定产能、工作时间,及每个工站每天的产能排配信息等。月出货需求计划表包括某一月所有货物的出厂计划信息,如出货日期、出货数量等。物料进厂计划表包括各种货物所涉及的物料的进厂计划信息,如进厂日期、数量等。The
所述主机10还连接有显示器20、键盘40及鼠标50。键盘40及鼠标50供用户在设置行事历资料及排程参数输入资料。显示器20提供一显示界面供用户浏览上述各种资料及排程所产生的资料。The
所述主机10包括资料读取模块110、参数设置模块120及生产计划排程模块130。The
资料读取模块110用于访问数据库30,从数据库30读取需要进行生产计划排程的订单资料、各工站产能排配资料、月出货需求计划表及物料进厂计划表等资料。The
参数设置模块120用于供用户设置行事历及设置排程参数。其中设置行事历是指设置各工站的正常上班时间与加班时间,可以周为单位或者以月份为单位设置行事历。设置排程参数包括设定订单排程的优先级别。设置排程参数还可以包括设置在后续的排程过程中是否考虑当前WIP库存情况。WIP库存是指订单的货物已经投入生产的数量,如果考虑当前WIP库存,则在后续的排程过程中,相应订单的需求数量应扣减掉当前的WIP库存数量。The
生产计划排程模块130用于根据所述月出货需求信息、物料进厂计划信息及所设定订单排程的优先级顺序等多重限制条件自动进行生产计划排程,将各订单所涉及的任务依据各工站的产能情况分配到各工站。The production planning and
如图2所示,是本发明生产计划自动排程方法较佳实施例的流程图。首先,于步骤S10,资料读取模块110访问数据库30,从数据库30中读取需要进行生产排程的订单资料及企业内部各工站的产能资料。其中,订单资料包括订单的交期、客户、订单货物的种类,订单需求的数量、完成一个订单所涉及的任务(投料、裁切、背胶贴合、……装配、入库)、各任务需经过的工站、任务经过工站的顺序等信息;各工站的产能资料包括各工站的平均产能、最大产能,各工站包含的机台数量,每个机台的固定产能、工作时间,及每个工站每天的产能排配等信息。As shown in FIG. 2 , it is a flow chart of a preferred embodiment of the automatic scheduling method for production planning of the present invention. Firstly, in step S10 , the
接下来,于步骤S12,资料读取模块110访问数据库30,从数据库30中读取月出货需求计划表,获取当月所有货物的出货计划信息。一般说来,“先出货先生产”是生产计划排配的主要原则之一。Next, in step S12, the
进一步地,于步骤S14,资料读取模块110访问数据库30,从数据库30中读取物料进厂计划表,获取各订单所涉及物料的进厂情况。“物料先进先出”也是生产计划排配的主要原则,如果两个订单A与B的计划出货日期相同,但订单B的加工原材料先进厂,则先对订单B进行生产计划排程。Further, in step S14, the
于步骤S16,用户通过参数设置模块120提供的界面设置行事历,即设置各工站的正常上班时间及加班时间。行事历设置可以周为单位或月份为单位,若以周为单位则设置一周中的正常上班时间及加班时间;若以月份为单位则设置某一月份中的正常上班时间及加班时间。In step S16, the user sets the calendar through the interface provided by the
行事历设置完毕后,于步骤S18,用户通过参数设置模块120提供的界面设置排程参数(如图3所示),所述排程参数包括设定订单排程的优先级别,如设定某一订单的某个工站作业的提前天数(如出货提前期为1天)。在各订单原计划的出货日期及物料进厂时间相同的情况下,根据所设定的订单的优先级别排配各订单的生产计划。进一步地,于步骤S20,用户判断参数设置是否考虑WIP库存状况。WIP库存是指订单的货物已经投入生产的数量。如果不考虑WIP库存状况,则直接进入步骤S24,生产计划排程模块130根据所述月出货需求信息、物料进厂计划信息及所设定订单排程的优先级顺序等多重限制条件自动进行生产计划排程,将各订单所涉及的任务依据各工站的产能情况分配到各工站。After the calendar is set, in step S18, the user sets the scheduling parameters through the interface provided by the parameter setting module 120 (as shown in FIG. 3 ). The scheduling parameters include setting the priority level of the order scheduling, such as setting a certain The number of days in advance of a station operation of an order (for example, the delivery lead time is 1 day). In the case that the original planned shipping date and material arrival time of each order are the same, arrange the production plan of each order according to the priority level of the set order. Further, in step S20, the user determines whether the parameter setting considers the WIP inventory status. WIP inventory refers to the quantity of goods ordered that have been put into production. If the WIP inventory situation is not considered, then go directly to step S24, and the production planning and
如果在步骤S20用户判断结果为考虑当前WIP库存,则进入步骤S22,资料读取模块110访问数据库30,查询当前各货物的WIP库存信息,生产计划排程模块130将相应订单的需求数量应扣减掉当前的WIP库存数量;之后,流程进入步骤S24。If the user judgment result in step S20 is to consider the current WIP inventory, then enter step S22, the
