針對現(xiàn)有工作流建模語言難以兼顧語言的可理解性、執(zhí)行語義的形式化和描述維度的單一性等問題，提出利用可視化的過程模型作為工
作流建模語言。過程模型能從過程、數(shù)據(jù)、資源、組織等多個(gè)角度描述企事業(yè)的業(yè)務(wù)工作流程。根據(jù)過程模型的語法和工作流系統(tǒng)的特點(diǎn)，定義
形式化執(zhí)行語義，為過程模型的分析、驗(yàn)證和執(zhí)行提供理論依據(jù)。

【Abstract】Current workflow modeling languages are difficult to balance both understandability and formal execution semantics. They can only
describe workflows in a single dimension. This paper suggests using process model as a workflow modeling language. Process model depicts the
business flows of enterprises from multi-dimensions such as process, data, resource and organization. Based on the syntax of process model and
characteristics of workflow systems, a formal execution semantics of process model is presented. The semantics is theoretical basis for model
analysis, verification and execution.
【Key words】workflow; process model; execution semantics
