Introduction
Supply chain management facilitates integration
between the customers, the distribution network,
internal enterprise activities and the supply [1]. This has
a predominant role in the competitiveness of companies
Consequently, there is a prevailing need to eliminate
operations that do not add value in processes, in order
to minimize cycle time, to increase productivity and
minimize inventory levels throughout the supply chain,
and at the same time improve product quality, and
customer satisfaction as high as possible. As a result,
supply chains are very vulnerable to disturbances, due to
unforeseen events in each process [2]. Consistent with this
approach Van der Vorst et al. [2-4] refer that food supply
more vulnerable, as they are products with a limited
life cycle, and high variability in availability, quality and
quantity of raw materials, and also the fact that the quality
of the product can change as it is transformed through
the different processes. These vulnerabilities make the
management of food supply chains more complex when it
comes to strengthening their performance.
In general, the vulnerability of supply chains is
key performance indicators (KPIs). The performance of
supply chains generates post-harvest losses that affect
product quality, productivity and costs, among others [2].
In today’s competitive business environment,
supply chain performance is one of the most critical
issues in various industries [5]. Supply chains are complex
in themselves, each component that is part of them
involves details that are essential to take into account in
decision-making, with the most up-to-date and accurate
information from all members of the chain [6].
A supply chain is a network of enterprises
that produce, sell, and deliver a product or service to
a predetermined market segment. It not only includes
producers and suppliers, but also carriers, storage,
retailers and own customers, among others [7]. According
to Yared Lemma and Gatew [8] supply chains are
composed by four logistics systems: supply, production,
merchandising and inverse logistics. In perishable food
supply chains, the supply logistic system is where the
greatest losses occur, and their causes are different
from developed and developing countries; in the later,
approximately 64% of the losses occur in the supply
infrastructure (such as transportation and storage), and
techniques for harvesting, transportation and storage.
In developed countries, losses along the entire value chain
of food products range between 40% and 50% of this 42%
come of total food waste and in developing countries,
losses can be as high as 30% to 50%, and 40% of that
losses occur at the post-harvest and processing level [9].
Now a days Cuba is immersed in a process of
transformations of its economy, to lay the foundations
for the economic development that allows to perfect its
socialist social system. This process is taking place within
alimentary, energetic and environmental crisis; in an
increasingly globalized environment. At the beginning of
these transformations, certain symptoms are manifested
concept, and the new concept of economy functioning
that is beginning to be instituted. At present the
individual management of each enterprise do not result
in high competitiveness, for that reason it is necessary to
integrate the management of the supply chain [10].
The research integrates various tools that
aquaculture industry, their application permits to
strengthen the process and the quality index method
is proposed as an indicator of system management and
reliability.
Materials and methods
The procedure depicted in Figure 1, allowed
to carry out a diagnosis of the supply logistics to the
applied in the different stages such as Failure Mode and
Effects Analysis (FMEA); and Variant Mode and Effects
Analysis (VMEA) that allow to identify and to classify the
disturbances in the chain and the proposed indicators
also the use of the quality index method (QIM), as well as
