The underlying objective of the paper is to identify and evaluate in the research process vital factors that impact the development of design and construction enterprises of photovoltaic farms on the energy markets, in particular narrowed down to renewable energy sources (RES) markets, including energy coming from photovoltaic sources. The first part of the paper, the epistemological one, introduces a scientific discourse pertaining to conditionings and restrictions related to RES markets in the dimensions of sustainable development. This has been done with the use of literature query, legislative and administrative acts, and reports drawn up for the European Commission. In this reference, we summarized the EU’s essential measures aimed at promoting the idea of sustainability. The second part of the paper, the empirical one, presents a summary of the results obtained within the research pertaining to “opportunities and threats in managing projects of photovoltaic farms in production enterprises of energy appliances”. The research was conducted in a group of 24 design and construction enterprises of photovoltaic farms. The concentration of the research, in the context of the underlying objective of this paper, pertained to the aggregation and evaluation of selected factors that stimulate the development and competitiveness of construction projects and the implementation of photovoltaic farms. We considered the hierarchy of strategic objectives of the investigated enterprises and selected threats to their market position. Two primary criteria were adopted to aggregate and evaluate vital factors that impact the development of design and construction enterprises of PV farms. The first of them is the qualitative one—top scores, weighted averages of respondent evaluations on the five-point Likert scale. The second one is the quantitative criterion—number of indications N ≥ 22 of the respondents (over 90%). A measurable value of the paper is the scientific discourse pertaining to dimensions of competitiveness of the investigated and analyzed enterprises on the RES market, in particular narrowed down to photovoltaic farms.

Bidding Process

AbstractThe authors aim to provide a set of tools to facilitate the main stages of the competitive bidding process for construction contractors. These involve 1) deciding whether to bid, 2) calculating the total price, and 3) breaking down the total price into the items of the bill of quantities or the schedule of payments to optimise contractor cash flows. To define factors that affect the decision to bid, the authors rely upon literature on the subject and put forward that multi-criteria methods are applied to calculate a single measure of contract attractiveness (utility value). An attractive contract implies that the contractor is likely to offer a lower price to increase chances of winning the competition. The total bid price is thus to be interpolated between the lowest acceptable and the highest justifiable price based on the contract attractiveness. With the total bid price established, the next step is to split it between the items of the schedule of payments. A linear programming model is proposed for this purpose. The application of the models is illustrated with a numerical example.The model produces an economically justified bid price together with its breakdown, maintaining the logical proportion between unit prices of particular items of the schedule of payment. Contrary to most methods presented in the literature, the method does not focus on the trade-off between probability of winning and the price but is solely devoted to defining the most reasonable price under project-specific circumstances.The approach proposed in the paper promotes a systematic approach to real-life bidding problems. It integrates practices observed in operation of construction enterprises and uses directly available input. It may facilitate establishing the contractor’s in-house procedures and managerial decision support systems for the pricing process.

An important component of successful economic activity of industrial enterprises is the optimal sales model combined with e-commerce opportunities. The article analyzed two construction materials manufacturing enterprises categories: those using exclusively a sales network for the promotion of their products, and those developing a direct sales system to the final consumer via electronic commerce. These are basically two different logistical approaches to the process of selling their own products. The efficiency of using e-commerce logistics means is determined by the correlation of sales expenses index with an indicator of enterprises' net income. It was proved sales expenses' indicator affects the dynamics of the net income indicator positively only for the enterprises using e-commerce logistics as a means of setting up a direct sales channel for their products. The article provides recommendations for creating an optimal logistics e-commerce system for construction materials manufacturing enterprises.
