Abstract The intensity of competition is typically measured according to the number bidders on any given public procurement market. By analysing Tenders Electronic Daily database 2017–2020, we examine conditions in contract notices which have an impact increasing launching procedures. research findings show that longer duration contract, lowest price awarding criteria, division subject matter into lots and possibility negotiations are essential elements can activate bidders.

This paper addresses issue relation to supplier ranking problem. It describes development a with cross-efficiency that incorporates into model. The we describe compared...
This paper offers a solution to the supplier selection problem and of lot‐sizing decisions. Data Envelopment Analysis (DEA) is seldom applied help solve multilevel problems. The order allocation reformulated as linear programming in novel way. First, Analysis/common weights model (DEA/CWA) introduced define pool capable suppliers. Selection criteria include management green criteria. In second phase, nonlinear mathematical programing offered determine capacity distribution among selected A...
