Now a day, green retail operations drive in many fields to improve the quality of deteriorating items during the delivery of the green items to his customer. In the present paper, retailer receives greening items from the seller and stores it. After received lot of greening items, retailer starts packing of greening items to maintain the quality of greening items and safe from some germs. We are considering that the holding units exit carbon units which are harmful to the environments. Retailer includes carbon emission cost and green packing cost and also invests on greening items to control the greening degree of the product. This paper deals a green economic order quantity (EOQ) inventory model with learning effect for decaying greening items under the inflationary condition and credit financing. An expression for the total cost of the retailer has been minimized with respect to cycle length in the environments of green operations. The objective of this paper is to analyze the impact of greening degree and trade‐credit financing with the learning effect and inflationary condition under carbon emissions on the retailer's total inventory cost. An expression for the total cost of the retailer has been minimized with respect to cycle length in the environments of green operations. Conclusively, sensitive analysis has been presented as a consequence of numerical examples.

Cancer is turning into the leading cause of death across the planet but with all of the details on how to expand complementary treatment strategies, it is continued to be a mystery. Mathematical models provide realistic representations and sizes of complex biological systems, as well as the clarification of organisms by their effects can provide insight into the shape predictions of the plant under different conditions. Also tumorigenesis can be understandable by the use of biomaterials and biomaterials have also ability to identify and capture tumor cells in vitro and in vivo. As to recapitulate key features of the tumor microenvironment in vitro, including architectural, mechanical, and biological functions, natural and synthetic biomaterials can be applied as models. In this work, a mathematical model is developed by using the delay differential equation methodology in which the discussion has been made on stability analysis with time delay.
