采购过程的概念建模：公钥基础设施的RFP案例研究
Conceptual Modeling of a Procurement Process: Case study of RFP for Public Key Infrastructure
摘要：
采购是指在规定时间内交付货物或服务的过程。该过程包括采购、需要满足的规格和招标通知等方面，如征求建议书（RFP）。通常情况下，这种RFP是用英语口头描述的，带有表格和图表，导致要求的规格不精确。有人建议使用BPMN图来指定RFP中包含的需求。本文是一个合并的三个主题：（一）采购开发，重点是操作规范的RFP，（二）公钥基础设施（PKI）作为一个RFP的主题，和（三）概念建模，产生一个图表作为补充的RFP，以澄清要求比传统的工具，如自然语言，表格和特设图。
英文摘要：
Procurement refers to a process resulting in delivery of goods or services within a set time period. The process includes aspects of purchasing, specifications to be met, and solicitation notifications as in the case of Request For Proposals (RFPs). Typically such an RFP is described in a verbal ad hoc fashion, in English, with tables and graphs, resulting in imprecise specifications of requirements. It has been proposed that BPMN diagrams be used to specify requirements to be included in RFP. This paper is a merger of three topics: (i) Procurement development with a focus on operational specification of RFP, (ii) Public key infrastructure (PKI) as an RFP subject, and (iii) Conceptual modeling that produces a diagram as a supplement to an RFP to clarify requirements more precisely than traditional tools such as natural language, tables, and ad hoc graphs.
