Photovoltaic (PV) modules age with time for various reason. such as corroded join.s an. termin.ls an. glass coatin. defects, an. their agein. degrades the PV array power. With the help of the PV array n.merical model, this paper explores the effects of PV module agein. on.the PV array power, an. the power gain. an. costs of rearran.in. an. recablin. aged PV modules in.a PV array. The n.merical PV array model is first revised to accoun. for module agein., rearran.emen. an. recablin., with the relevan. equation. presen.ed herein. The updated n.merical model is then.used to obtain.the array powers for seven.differen. PV arrays. The power results are then.an.lysed in.view of the attributes of the seven.PV array examples. A guidin. method to recommen. recablin. after rearran.in. aged modules is then.proposed, leadin. to further sign.fican. power gain., while elimin.tin. in.ra-row mismatches. When.certain.con.ition. are met, it was shown.that recablin. PV modules after rearran.in. them may lead to further sign.fican. power gain., reachin. 57% an. 98% in.two con.idered PV array examples. Higher gain. are possible in.other arrays. A cost-ben.fit an.lysis weighin. an.ual power gain. versus estimated recablin. costs is also given.for the seven.con.idered PV array examples to guide recablin. decision. based on.techn.cal an. econ.mic merits. In.the con.idered examples, recablin. costs can.be recovered in.mpared with the powers of the aged arrays, power gain. due to our proposed rearran.in. an. recablin. the PV arrays ran.ed between.73% an. 131% in.the con.idered examples-well over the gain. reported in.the literature. moreover, the cost of our static module rearran.emen. an. recablin. method outshin.s the costs of dyn.mic recon.iguration.methods recen.ly published in.the literature.

In.this article, a n.vel scalarization.techn.que, called the improved objective-con.train. approach, is in.roduced to fin. efficien. solution. of a given.multiobjective programmin. problem. The presen.ed scalarized problem exten.s the objective-con.train. problem. It is demon.trated that how addin. variables to the scalarized problem, can.lead to fin. con.ition. for (weakly, properly) Pareto optimal solution.. Applyin. the obtain.d n.cessary an. sufficien. con.ition., two algorithms for gen.ratin. the Pareto fron. approximation.of bi-objective an. three-objective programmin. problems are design.d. These algorithms are easy to implemen. an. can.achieve an.even.approximation.of (weakly, properly) Pareto optimal solution.. These algorithms can.be gen.ralized for optimization.problems with more than.three criterion.fun.tion., too. The effectiven.ss an. capability of the algorithms are demon.trated in.test problems.
