Abstract

The success of a construction project can be said to be successful if it meets several aspects, according to its development the level of success must at least be met from the aspects of Cost, Quality, Time, and SMKK (construction safety management system). Each of these aspects has its own parameters, so the overall achievement is needed so that success can be achieved. If we assume that this aspect is a function, then we can formulate it as follows:
fj (x1,....., xn) = a(j,1).x(j,1)^(P(j,1)) + ... + a(j,n).x(j,n)^(P(j,n))
fk (x1,....., xn) = b(k,1).x(k,1)^(P(k,1)) + ... + a(k,n).x(k,n)^(P(k,n))
fl (x1,....., xn) = c(l,1).x(l,1)^(P(l,1))+ ... + a(l,n).x(l,n)^(P(l,n))
fm (x1,....., xn) = c(m,1).x(m,1)^(P(m,1)) + ... + a(m,n).x(m,n)^(P(m,n))
in which :
fj = function of cost
fk = function of quality
fl = function of time
fm = function of SMKK
a(j) = Coefficient /quality for x(j)
b(k) = Coefficient /quality for x(k)
c(l) = Coefficient /quality for x(l)
d(m) = Coefficient /quality for x(m)
Pjn, Pkn, Pln, Pmn, where -~ < p(j), p(k), p(l), p(m) < ~ (a constant where value is between negative infinity and infinity)
By taking a function-based approach, we can map out that the efficiency value in the function at which point is the optimum result. So that the mapping based on these functions can provide an understanding of the parameters that can provide the best results in the success of a construction project.
