================================================================================ P9307 A. Stins & A. Schoneveld "Specification of a bank account with process algebra" The aim of this report is to specify a private bank account. This report covers the description of some significant processes and actions between the client and the bank. Before starting off, we want to take a look at the function of a bank account from the viewpoint of a bank. We will use the theory ACP [BW90] to specify the bank account without taking time into consideration ACPdt [BB92] will be the theory we will use to specify the bank account with time. [BW90] J.C.M.
