The present paper regards the opportunities of forecasting of some key indicators in the “Request for Information” (RFI) and “Request for Proposal” (RFP) processes in the supply chain at the Bulgarian mobile telecommunication operators. The presented hereby forecasting is based on the use of the Holt-Winters method for exponential smoothing in the presence of additive and multiplicative seasonality and is made or indicators: “number of contracts”, “number of contracts with savings” and “number of the issued purchase orders”. The lowest “Stationary R square”, “R square” and MAPE (Mean Absolute Percentage of Error) values are used as measurement of accuracy and for selection of the best fit models that are applied. It is also important to point out that the measurement is being done for the so-called “bottle necks” or “narrow places” in the RFI and RFP processes. The purpose of this bottle-neck forecasting is to provide timely point for “Go/Not Go” decisions point for these very same process and thus to result in an improved risk management in the form of risk aversion and risk minimization.

Supply Chain Orientation

The present study examines the management of transaction risks in supply chains. Risk management studies often ignore the wider supply chain context in which individual transactions take place. However, risk management strategies which are suitable to use when only a single transaction is considered may be inappropriate when other transactions in the supply chain are taken into account. This study addresses this issue by examining: (1) how risks arise as a result of interdependencies between the various transactions making up the supply chain; and (2) what types of contractual-based strategies actors can use to manage their risk exposure. To realize these aims, the study applies an extended Transaction Cost Economics (TCE) framework with a supply chain orientation. The framework illustrates how different types of interdependencies - pooled, sequential and reciprocal - expose companies to different sources of risk. Three strategies companies can use when facing barriers to risk minimization in sequentially interdependent supply chains are analyzed: risk transferring, risk altering and risk sharing. Examples from the agri-food sector are discussed to demonstrate the functioning of these strategies.

The present paper regards some the score cards as a possible tool for measurement and evaluation of the risk in the “Request for Information” (RFI) and “Request for Proposal” (RFP) processes in the supply chain at the Bulgarian mobile telecommunication operators. The presented hereby score cards use measurement and calculations of the risk based on the risk calculation equation in which the assumption is that each risk event or risk action “m” can be regarded as function of the likelihood of occurrence, the consequences and the imminence in regards to the time horizon for the occurrence of the very same risk event or risk action “m”. Further to these components, the risk equation in use also takes into account the space in which the risk occurs and itself, as well as the size of the actions for prevention and overcoming of the risks that can appear at a certain organizational level. The data collected for the score cards is being provided by an online survey through the staff dealing with the RFI and RFP processes within the regarded in particular Bulgarian telecommunication operator. The final information from both the survey and the score cards is being processed and turned into a specific set of numeric coefficients that represent the contribution and the value of the separate risk components. Methods for defining the thresholds for acceptance of the levels of the risks are also suggested.

Abstract Reliability is one of the most important characteristics of the functioning of supply chains. The carried out analysis have shown that, despite some progress, a number of questions remain open, in particular, the terminology, the selection of key indicators and methods of their calculation as well as there is no economic evaluation of redundant and restorable supply chains. The paper presents a formed conceptual apparatus of logistics systems' reliability theory, the discrete-continuous model of the simple supply chain’s functioning as well as it contains the proposal to assess the reliability not only with the help of faultlessness but as well by using the leading function of costs associated with the maintenance of supply chains’ operability

Abstract Supply chain risk management (SCRM) has been widely discussed in the academic literature and several models have been proposed in recent years, but there is a need for a model encompassing phases and tools for SCRM. This study presents a systematic literature review (SLR) of 254 abstracts and 68 full-text papers. The SLR made it possible to identify and define the main phases for the SCRM, as well as the tools proposed for each phase. There is a concentration of efforts in the phases of identification, assessment, and selection of risk management strategies and a limited number of studies in monitoring and controlling risks. The article offers a global SCRM framework, contributing to the theoretical discussions and a practical guide to implementation related to SCRM.

Purpose Risk management in supply chain (SC) is not an easy task due to different uncertainty and intricacy. Management of risk is necessary for smooth operation of SC. The purpose of this paper is to demonstrate multi-criteria decision-making (MCDM) approaches to select the best SC which has minimum risks. Design/methodology/approach In proposed methodologies different steps, i.e. goal, risk attributes, risk sub-attributes and alternatives are identified for the selection of best SC using analytical network process which is being followed by the Multi-Objective Optimization by Rational Analysis method. Findings Findings of this paper are highly valuable for Indian manufacturing industries for risk management in SC. It helps the researchers and managers to deal with different types of uncertainty and risks associated with SC. Research limitations/implications This research is limited only for risk management in SC. Other issues in SC can be analyzed and further extended by other MCDM approaches. Originality/value This paper identified the different risks in SC and a systematic way to find out the best SC which helps the researchers and managers in risk mitigation.
