PurposeThis study aims to create a reliable, collaborative and sustainable business environment with suppliers of a company for providing high-quality and low-cost products on time. A supplier management system that sustains existing suppliers by sharing work based on systematic performance evaluation while developing the supplier base with potential suppliers is proposed.Design/methodology/approachBuilt on quantitative approaches, supplier management functions are integrated in the designed system. A quantitative strengths, weaknesses, opportunities and threats (SWOT) analysis is adapted for evaluating potential suppliers. A multi-objective integer linear programming (ILP) model is developed for the distribution of orders among selected potential and existing suppliers. A performance evaluation scheme based on an exponentially weighted moving average (EWMA) is proposed to evaluate and monitor suppliers' performance over time.FindingsProposed system develops a supplier base by methodically selecting and approving new suppliers, and a sustainable relationship with both new and existing suppliers is established based on performance over time. Decisions on retaining or removing suppliers from the base are objectively made by quantitative evaluations. Orders are fairly distributed among suppliers under the constraints imposed by the management. Dependence on a certain set of suppliers and its associated risks are reduced while agility in offering goods is enabled.Originality/valueBusiness processes for selecting new suppliers, distributing orders among all suppliers, evaluating and monitoring performance over time are quantitatively integrated to add value in operational decision-making. The proposed system is original in the holistic approach for managing and sustaining multiple suppliers of a company based on performance.

The purpose of the study, is to formulate the concept of "online video advertising " as an object of online marketing, to generalize its types and build a system of performance evaluation indicators. Based on the study of interpretation and content of the definition of "advertising" and its types, presented by different scientific domestic and foreign schools and scientists, the authors derived the definition of "online video advertising" by highlighting the features of advertising, and also presented the typology of video advertising on the Internet based on the proposed classification attributes: the location, technical execution, and task of video advertising. The authors also proposed a system to assess the effectiveness of online video advertising based on two groups of metrics: primary (determined based on the actions of online users) and targeted (aimed at assessing the specific goals of the marketing campaign), which can objectively evaluate the success and productivity of video advertising.
