Abstract
In our earlier paper (1), the necessity and method of analysis on the planning process of social facility and some results were shown. The aim of this paper is to analyze on the information system in the planning process and to clssify the facilities according to the similarity of information processing. The information flow and density in each planning process is constructed through putting in order to the official documents and informations as figure 3-1. The information density is increasing with processing of planning, the third planning cycle, where the cycle composed of a series [PLAN]→[DO]→[SEE] was shown in earlier paper, is disturbed by a great deal of information processing. A co-ordinating system, communicating with the externals and processing information, is needed in planning section. In order to analyze the information network of planning process, some following coefficients are defined : 1) I_<WR(ij)>=a_<ij>/a_<ii> (Information Wrap Ratio), 2) A_i=1/nΣ^^n___<j=1>I_<WR(ij)>, 3) B_i=1/nΣ^^n___<j=1>I_<WR(ij)>, 4) C_i=A_i/B_i, 5) D_i=√<A_i×B_i> and 6) Y_<ij>={a_<ij>d_<ij>-b_<ij>c_<ij>}/{a_<ij>d_<ij>+b_<ij>c_<ij>} (Yule coefficient) where a_<ij<, b_<ij<, c_<ij< and d_<ij< are frequence of information concerned with i-th and j-th facilities, i-th and not j-th, j-th and not i-th, and neither i-th nor j-th facilities. According to the analyses with the above coefficients, the main facilities in planning process are kindergarten, shops, primary scool and clinic, the other hand assembly room for habitant and parking area are depended on the main facilities. It is need to re-examine the planning of facilities such an assembly room from a viewpoint of possibility for community.
