Abstract

Location of private or public facilities is an important factor in determining their use, popularity and consequently profitability of facilities.

We inquire about the optimal location of playgrounds aimed for small children.

In this work we will introduce several models to optimize the location of playgrounds, under alternative scenarios.

At present, there are about 150 playgrounds in Haifa. Very few neighborhoods lack a playground at all. Many of the playgrounds were constructed a long time ago, and now they do not meet the mandatory safety regulations. The municipality is interested in the question - which of those playgrounds has to be dismounted and which has to be upgraded to be safe. The municipality provided us with data on the playgrounds.

In this work I will use two optimization scenarios. In the first scenario I will try to answer the question “where should we construct a playground, and how many of them, in addition to existing playgrounds to maximize the demand covered with service within a predetermined distance?” The results show that at present playgrounds are located not optimally - the existing playgrounds could cover considerably larger demands, than it does at present.

In the second scenario we answer the question “if we approach active and non active playgrounds (in Haifa) as potential construction sites, where should we construct playgrounds to maximize the demand covered within a predetermined distance?” Using operation research models we receive a considerable saving in funds relative to the results of the first scenario, and at the same time we can provide service to a greater part of the children's population in Haifa. Also, we checked whether it is economical to construct playgrounds which are in the optimal solution for every stated distance by comparing revenues and costs. Our findings show that the number of profitable playgrounds is very low. If we construct just profitable playgrounds, they will be crowded, and the walking distance will be very high. In terms of welfare economics net profitability is not a criterion to be adopted. Walking distance and no congestion are more important.
