        <p>Both environmental sustainability and the production of green products are strategies that are dictated by the need for environmental protection and modern business management practices, but still they are not widely applied. Adopting such strategies gives businesses the ability to operate more efficiently and develop a competitive advantage. This article proposes the theoretical development of a strategic framework using operations research models and business management tools aiming to develop a competitive advantage through sustainable environmental management.</p>

      <title>1 Introduction</title>
      <p>
        Worrying phenomena such as the climate change, the increase in average
temperatures and the greenhouse gases emissions lead to increasingly negative
environmental and economic impacts, which need to be treated effectively
        <xref ref-type="bibr" rid="ref30">(Papageorgiou et al., 2015)</xref>
        . This relationship between economic development,
energy consumption, gas emissions and their negative implications is analyzed in
several studies
        <xref ref-type="bibr" rid="ref26 ref26 ref6 ref6">(Chalikias &amp; Ntanos, 2015; Ntanos et al, 2015)</xref>
        . In recent decades,
businesses have been faced with a set of new challenges in environmental
management. In addition, the need for environmentally friendly products becomes
increasingly imperative as consumers’ exhibit increased awareness towards
environmental issues and renewable energy sources

        The current environment in which businesses are required to operate is very
dynamic, similar to the environment of a battle. For the analysis of such
environments, operations research models have been developed and can be applied in
the case of enterprises

and
competitive
In recent years, more and more businesses are turning to practices aiming at
environmental protection and sustainability. On the one hand, this trend stems from
the increasing pressure from stakeholders, such as environmental organizations,
consumers and regulators. In this sense, environmental sustainability could be the
most important challenge of corporate social responsibility. On the other hand, the
trend towards integrating sustainable management of the environment into business
strategy has to do with its contribution to competitive advantage creation.</p>
      <p>
        Corporate social responsibility is inseparably linked to environmental protection.
Corporate social responsibility contributes to corporate image strengthening, to
favorable taxation promotion, to relations with the stakeholders strengthening as well
as to better risk management and security
        <xref ref-type="bibr" rid="ref37">(Urip, 2010)</xref>
        . Consequently, actions related
to environmental protection and can be expressed through corporate social
responsibility framework can lead to higher economic returns and as far as it is
concerned to the establishment of a competitive advantage
        <xref ref-type="bibr" rid="ref35 ref37">(Urip, 2010; Skordoulis et
al. 2013)</xref>
        .
      </p>
      <p>
        According to Danjelico and Pujari (2010), sustainable environmental management
is linked to the competitive advantage of a business by reducing the use of energy,
raw materials and pollutants. According to them, the production of green products,
i.e. products produced by methods that minimize the burden on the environment
        <xref ref-type="bibr" rid="ref29">(Ottman et al., 2006)</xref>
        .
      </p>
      <p>Wu and Lin (2016) report that green product production contributes to minimizing
the environmental impact of products throughout their lifetime, including purchasing
raw materials, manufacturing, selling, consumption and disposal after use.</p>
      <p>According to a framework proposed by Rohm and Montgomery (2010), revenue
growth, risk reduction and cost reduction will increase business profitability and lead
to a sustainable competitive advantage.</p>
      <p>More specifically, a strong emphasis on sustainability leads to the development of
more eco-efficient products, strengthens co-operation with environmental regulators
and reduces the environmental impact of business operations.</p>
      <p>In addition, new technological capabilities are created to help measure and analyze
environmental impacts more effectively.</p>
      <p>Furthermore, by producing more eco-efficient products, higher value can be
provided to an increasing number of green consumers, which will lead to increased
sales.</p>
      <p>
        Moreover, a better and more efficient co-operation with environment regulators
will be archived through the production of green products. This will reduce business
risk, since eco-friendly and safe products will reduce the potential risk of
environmental liability and consumers. This reduced risk will have a positive impact
on capital costs. In turn, actions to reduce production processes impact on the
environment will lead to direct cost savings of fuel, water, electricity and waste
disposal

      </p>
      <p>
        It is a fact that the cost of organizing a business to operate with a focus on
sustainable environmental management can be considered quite high. However,
businesses should not perceive the adoption of sustainable environmental
management practices as unnecessary costs; they should perceive them as long-term
investments that eventually lead to the development of a competitive advantage

      <title>3 Business competition analysis with operations research models and strategy formulation</title>
      <p>During the World Wars, mathematical models were widely used in combats. These
models aimed at solving various optimization problems related to the ongoing war
operations. By the end of the wars, these models were applied with to business cases,
since business competition is very similar to battlefields combats.</p>
      <p>
        Such models based on differential equations have been applied in business cases
such as marketing strategy analysis
        <xref ref-type="bibr" rid="ref36">(Taoka, 1997)</xref>
        , oligopoly competition strategies
        <xref ref-type="bibr" rid="ref17">(Fruchter &amp; Kalish, 1997)</xref>
        , products development based on customers’ needs
        <xref ref-type="bibr" rid="ref15">(Fehlmann, 2008)</xref>
        , advertising costs
        <xref ref-type="bibr" rid="ref12 ref7 ref8 ref9">(Chintagunta &amp; Vilcassim, 1992; Chalikias &amp;
Skordoulis, 2014; Chalikias et al. 2016)</xref>
        and supply chains
        <xref ref-type="bibr" rid="ref8 ref9">(Chalikias &amp; Skordoulis,
2016)</xref>
        .
      </p>
      <p>
        Unlike traditional static models that can only explain competition in a market,
operations research models such as Lanchester’s combat model can not only be used
in the multidimensional analysis of a market but also in the prediction of tis future
sizes based on competition data
        <xref ref-type="bibr" rid="ref15">(Fehlmann, 2008)</xref>
        .
      </p>
      <p>In such a case, the competition between two businesses could be analyzed by a
system of differential equations as the following one:
⎡ dx</p>
      <p>= −ay + f (t)
⎢ dt
⎢
⎢ dy = −bx + g(t)
⎢⎣ dt
(1)</p>
      <p>Where x (t) and y (t) would be the operating income for each one of the two
competitors, f (t) and g (t) the rate at which they increase or decrease affected by one
or more variables in each model. Such variables would be advertising costs, supplies
at points of sale, or environmental investments.</p>
      <p>
        Having analyzed the competition with an operations research model it is possible
to point out the strengths and weaknesses of a business against competition as well as
the points that need to be improved
        <xref ref-type="bibr" rid="ref15">(Fehlmann, 2008)</xref>
        .
      </p>
      <p>Once the strengths, weaknesses and the points to be improved have been recorded,
the next step is to develop the appropriate business strategy. For this purpose, tools of
modern business administration can be used.</p>
      <p>
        Such a tool is the Quality Function Deployment (QFD) method, which aims to
integrate customers’ needs and requirements at the development of a product
        <xref ref-type="bibr" rid="ref10">(Felhmann, 2008; Chaudha et al., 2011)</xref>
        . The QFD method can indicate to a business
where and how to focus as well as the impacts on competition
        <xref ref-type="bibr" rid="ref33">(Salari &amp; Bhuiyan,
2016)</xref>
        .
      </p>
      <p>
        Environmental sustainability through the QFD method means that a business
should operate environmentally responsible
        <xref ref-type="bibr" rid="ref13">(Dai &amp; Blackhurst, 2012)</xref>
        and should
therefore translate environmental requirements into processes; this strategy would
possibly result in the potential development of a competitive advantage as already
discussed.
      </p>
      <p>
        Another tool that could be used to achieve environmental sustainability is the
Balanced Scorecard (BSC), the basic idea of which is that the effective use of
investment funds is no longer the only determinant of developing a competitive
advantage, but there are other factors as well such as human capital, knowledge
creation and customer orientation
        <xref ref-type="bibr" rid="ref20">(Kaplan &amp; Norton, 2005)</xref>
        .
      </p>
      <p>In order to apply BSC method to an environmental sustainability strategy, the
proper business units should be selected, the environmental aspects must identified,
and the relationship between the environmental aspects and the business strategy
should be analyzed (Figgie Et al., 2002).</p>
      <p>
        By adding the environmental dimension to BSC, in addition to its existing ones, a
business can translate its environmental strategy into a set of performance and
requirements measures
        <xref ref-type="bibr" rid="ref34">(Sidiropoulos et al., 2004)</xref>
        . The elements that may include the
environmental dimension of a BSC are presented in the table below.
      </p>
      <p>
        Based on the above framework, the environmental dimension of BSC can be used
to model different events to provide the ability to run, analyze and evaluate different
scenarios
        <xref ref-type="bibr" rid="ref34">(Sidiropoulos et al., 2004)</xref>
        .
      </p>
    </sec>

      <title>4 Conclusions</title>
      <p>
        The fact that many businesses do not yet consider environmental sustainability as a
priority
        <xref ref-type="bibr" rid="ref19">(Kaebernick et al., 2003)</xref>
        gives to those who integer it into their strategies the
chance to develop a competitive advantage. This will be the results of both the
benefits provided by an environmental sustainability strategy
        <xref ref-type="bibr" rid="ref21">(Kim &amp; Mauborgne,
2005)</xref>
        and, a so-called “blue ocean” strategy which is an innovative approach that
enables development in new fields of a market where there are still few potential
competitors
        <xref ref-type="bibr" rid="ref25">(Nidumolu et al., 2009)</xref>
        .
      </p>
      <p>From the above analysis, it is obvious that integrating environmental requirements
into business strategy leads to a sustainability framework that can be reflected by the
development of a competitive advantage by improving efficiency, reducing costs and
risks and increasing compatibility with customers’ and regulations’ requirements.</p>
      <p>
        Developing an environmental sustainability strategy through operations research
models and business management tools is more effective than traditional ways since
it takes into account all possible variables and it is possible to predict the results by
creating, running and evaluating different scenarios
        <xref ref-type="bibr" rid="ref31 ref39">(White &amp; Lee, 2009;
PaucarCaceres &amp; Espinosa, 2011)</xref>
        .
      </p>
      <p>Therefore, a business strategy that includes environmental sustainability will be
more effective when it is based on operations research model and business tools such
as the QFD method, as this will provide a better understanding of the competition
and the requirements. Moreover, the analysis of as many scenarios as possible
including different variables will become feasible.</p>
      <p>A strategic approach as described above will result in significant changes in the
structure, the mission, the vision and the purpose of any business that will adopt it.
Such a strategy can ultimately enhance the reputation and results of a business in a
constantly changing market that creates new challenges.</p>
