Abstract
Space are often used in double or manifold ways. Japanese have been making use of a room for various uses by means of Funitur. Such convertibilyty of space catches hout eyes today for economy, and many examples of doubled or manifold uses of space are seen when similarity on the function and circumstance of frequence of use are favorable. As study of quantitative treatment was made on such cares by means of the theory of queues applying the cares of hyper-exponential service and hyper-poisson arrival. Though it it is not complete as a method, it may suggeste a transitional one. Examples of a wayer closet in a dwelling house a service case of hyper-exponential service, and conference rooms etc, a office building as a case of hyper-poisson arrival, are discussed.
