Y (SocI), is determined within this study within the type of a vector value [34]. The degree of organization model sustainability inside the proposed methodological approachcan be regarded a benchmark if SV = (1; 1; 1). Therefore, this study assumes that the deviation from the company model efficiency vector demonstrates the deviation from the degree of its benchmark sustainability. Conversely, approaching the reference vector demonstrates the strengthening of its sustainability level (Figure 1).Sustainability 2021, 13,directions of financial efficiency (EcI), environmental efficiency (EnvI) and social efficiency (SocI), is determined within this study in the type of a vector worth [34]. The amount of company model sustainability in the proposed methodological approach may be regarded a benchmark if = (1; 1; 1). Hence, this study assumes that the deviation with the enterprise model efficiency vector demonstrates the deviation from the 9 of 22 level of its benchmark sustainability. Conversely, approaching the reference vector demonstrates the strengthening of its sustainability level (Figure 1).Figure 1. Scheme of organization model sustainability vector construction. (Source: own development Figure 1. Scheme of business model sustainability vector construction. (Supply: personal development depending on information from [35]). according to information from [35]).Figure 1 shows the scheme of determining the vector of sustainable small business model based on the proposed indicators (directions). The worth of the vector of sustainablebusiness model SV = (EcI; EnvI; SocI) is defined as the diagonal of a rectangular parallelepiped, which is developed by the coordinates from the vectors EcIi ; EnvI j ; SocIk as follows:|SV | =where,EcI2 + EnvI2 + SocI(31)SV–the length of Small business model sustainability vector; EcI–Business model economic efficiency indicator; EnvI–Business model environmental efficiency indicator; SocI–Business model social efficiency indicator. Values on the indicators EcI, EnvI and SocI, in line with the specified model, are determined by calculating the arithmetic typical with the indicator, which is integrated within the structure of those indicators. By way of example, the value EcI is determined on the basis of such normalized indicators because the coefficient of economic Hydroxyflutamide supplier independence (ind1 ), absolute liquidity ratio (ind2 ) and sales profitability (ind3 ). The degree of EnvI is defined around the basis of such normalized indicators because the efficiency of investment in environmental innovation (ind4 ), recycling rate (ind5 ) plus the index of energy-saving technologies (ind6 ). SocI contains such indicators as the rate of return (ind7 ), turnover rate (ind8 ) as well as the number of programs and projects for vulnerable populations (ind9 ). Therefore, the amount of company model sustainability will be the angle among the vector obtained from the outcomes of BI-0115 Inhibitor assessing its effectiveness in the 3 directions and also the reference vector, which can be determined by the formula.=12 + 12 + 12 ,(32)The angle formed involving the sustainability vectors in the company model might be determined in degrees by the following formula [34]: = arccos EcI + EnvI + SocI nEcI2 + EnvI2 + SocI2 , (33)Sustainability 2021, 13,10 ofwhere, –the angle in between the vector obtained by assessing the effectiveness on the small business model within the three directions, and the reference vector of its sustainability; n–the number of indicators (directions) of diagnosing the amount of business enterprise model sustainability. This angle is between 0 max , exactly where max ca.
