Boolean and relational operations, which are defined for solving mathematically logical problems,are always required in computing models. Membrane computing is a kind of distributed parallel computing model.In this paper, we design different membranes for implementing primary Boolean and relational operations respectively. And based on these membranes, a membrane system can be constructed by a present algorithm for evaluating a logical expression. Some examples are given to illustrate how to perform the Boolean, relational operations and evaluate the logical expression correctly in these membrane systems.
