[简答题] 老白在绿色化工公司人力资源部当助理，最近副总经理李勤直接委派他在10天内拟出一份本公司五年人力资源计划。其实老白已经把这任务仔细看过好几遍了。他觉得要编制好这个计划，必须考虑下列各项关键因素：首先是本公司现状。公司共有生产工具与维修工人825人，行政和文秘性白领职员143人，基层与中层管理干部79人，工程技术人员38人，销售员23人。其次，据统计，近五年来员工的离职率为4%，没理由预计会有什么改变。不过，不同类的员工的离职率并不一样，生产工人离职率高达8%，而技术和管理干部则只有3%。再则，按照既定的扩产计划，白领职员和销售员要新增10%到15%，工程技术人员要增5%-6%，中、基层干部不增也不减，而生产与维修的蓝领工人要增加5%。有一点特殊情况要考虑：最近本地政府颁发一项政策，要求当地企业招收新员工时，要优先照顾妇女和下岗员工。本公司一直未曾有意地排斥妇女或下岗职工，只要他们来申请，就会按同一种标准进行选拔，并无歧视，但也未予特殊照顾。如今的事实却是，几乎全部销售员都是男的，只有一位女销售员，中、基层管理干部除两人是妇女外，其余也都是男的；工程师里只有三个妇女；蓝领工人中约有11%是妇女或下岗职工，而且都是集中在最低层的劳动岗位上。白助理还有七天就得交出计划，其中得包括各类干部和员工的人数，要从外界招收的各类人员的人数以及如何贯彻市政府关于照顾妇女与下岗人员政策的计划。此外，绿色化工公司刚开发出几种有吸引力的新产品，所以预计公司销售额五年内会翻一番，他还得提出一项应变计划以备应付这种快速增长。在预测公司人力资源需求时，他能采用哪些计算技术？
